3408b Eddie Collins: Legends of baseball Ceremony Program.
A ceremony is usually held at the official first day city for every stamp and postal stationery item.
The city is usually selected for its relationship to the stamp's subject or because a philatelic event is occurring there.
People related to the stamp's subject are often invited to attend the ceremony along with political and postal officials. These invited guests are usually listed in the program.
An official ceremony program is produced by the USPS (USPOD before July 1971) or the sponsoring organization.
It's in very good shape, with minor edge wear areas and was issued on July 6, 2000.
