Private Collection of 358 United States Post Office Lobby Sheets. Dates from 1962 to 1981. Size of sheets: 10.5" by 8". These sheets came from a private collector.
They date from 1962 to 1981. 358 Total number of lobby sheets. Some are in never used condition. Some are folded in thirds, torn, marked in ink or pencil, or have small push pin marks where they were used on a bulletin board to display. There are some duplicates in this collection.
These were used by the Post Office to announce new released stamps. Happy to help if I can.
