                  Amendment No. 1 to Statement on Schedule 13D

     This  amended  statement  on Schedule  13D relates to the Common Stock (the
"Shares") of Putnam New York Investment  Grade Municipal  Trust, a Massachusetts
business trust (the "Company").  Items 4, 6 and 7 of this statement,  previously
filed by (i) the Mildred B. Horejsi Trust (the "Mildred  Trust"),  as the direct
beneficial owner of Shares and (ii) by virtue of certain relationships described
in this statement, by Stewart R. Horejsi, are hereby amended as set forth below.

Item 4. Purpose of Transaction

     No change except for the addition of the following:

     The Mildred Trust  originally  acquired Shares for the purpose of acquiring
an equity  ownership  of the  Company  and  asserting  control  of the  Company.
However,  on March 19, 2007,  the trustees of the Putnam  California  Investment
Grade  Municipal  Trust  ("PCA"),   took  steps  to  liquidate  PCA,  without  a
shareholder vote, in response to the Mildred Trust's tender offer to acquire all
of the outstanding  shares of PCA at a price of $15 per share.  The PCA trustees
stated that they took this approach in light of the fact that  approximately 20%
of PCA's shares had been tendered to the Mildred Trust in response to the tender
offer and PCA's trustees concluded that approval of their plan to merge PCA into
an open-end  Putnam  fund would not be approved in light of the Mildred  Trust's
opposition to the proposed merger. On March 21, 2007, the Mildred Trust sought a
preliminary  injunction  against  PCA's  liquidation  plan,  on grounds that the
trustees'  approval of a plan which would result in PCA  shareholders  receiving
less  than the  price  offered  in the  tender  offer  constituted  a breach  of
fiduciary  duty  and  that  the  liquidation  plan  should  be  approved  by PCA
shareholders.  On March 26, 2007, the Massachusetts  Superior Court rejected the
Mildred Trust's request for a preliminary injunction against the PCA liquidation
plan,  and,  as a result,  the Mildred  Trust was forced to withdraw  its tender
offer,  which could not be closed  given that  trading in PCA's shares was to be
halted prior to the time the tender offer expired.

     The Mildred  Trust  believes that the trustees of the Company will employ a
similar  strategy to  liquidate  the Company in response to the Mildred  Trust's
seeking  control of the Company in lieu of submitting the proposed merger of the
Company into a Putnam open-end fund to the Company's shareholders.  Accordingly,
the  Mildred  Trust does not  currently  believe it can  acquire  control of the
Company and thus does not  anticipate  that it will  continue to seek control of
the Company.  Instead, the Mildred Trust may from time to time dispose of all or
a portion  of the  Shares it owns or cease  selling  Shares.  Any such  sales of
Shares may be in open market, in privately-negotiated transactions or otherwise,
and will depend upon the Mildred Trust's evaluation of the Company's investments
and  prospects,  and upon future  developments  (including,  but not limited to,
performance  of the  Company's  equity  securities,  including the Shares in the
market,  effective yield on the Shares or other equity securities,  availability
of funds,  alternative uses of funds,  leveraged assets, money, stock market and
general economic conditions).

Item 6. Contracts, Arrangements, Understandings or Relationships with Respect to
Securities of the Issuer.

     No change except for the addition of the following:

     On March 9, 2007,  the Mildred  Trust entered into  agreements  with Karpus
Management,  Inc. concerning voting of the Shares acquired by the Mildred Trust.
A copy of the Form of Durable Power of Attorney by and between Stephen C. Miller
and Joel L.  Terwilliger,  acting as attorneys for the Mildred Trust, and Karpus
Investment Management,  Inc. and the Form of Irrevocable Proxy granted by Karpus
Investment Management, Inc. to Stephen C. Miller and Joel L. Terwilliger, acting
as  attorneys  for the  Mildred  Trust  are  filed as  Exhibits  3 and 4 to this
statement and incorporated herein by this reference.


Item 7. Material Filed as Exhibits.

     No change except for the addition of the following:

     Exhibit 3 Form of  Durable  Power of  Attorney  by and  between  Stephen C.
Miller and Joel L.  Terwilliger,  acting as attorneys for the Mildred Trust, and
Karpus Investment Management, Inc.

     Exhibit  4  Form  of  Irrevocable   Proxy  granted  by  Karpus   Investment
Management,  Inc.  to  Stephen  C.  Miller  and Joel L.  Terwilliger,  acting as
attorneys for the Mildred Trust.

                                    Signature

     After  reasonable  inquiry and to the best of my  knowledge  and belief,  I
certify that the information  set forth in this statement is true,  complete and
correct.
