Scott National Series Album Pages: U.S. Postal Stationery 2005-07 Supplement #57 
 
This supplement contains a total of 4 pages. Page 1 updates and replaces page 1 of Supplement No. 56 (2004).
 
Note: Priority envelopes Scott U652, U658, U660 and U661 are too large to fit on an album page and are therefore not included.
 
All stationery issued through May 12, 2007, as listed in the Scott Catalogue, are included.
