13 Cut Billboards
:
8
of the Lionel postwar billboards are marked “Standard” on the front and were in production from 1950 to 1956.
5
of the billboards are not marked “Standard” - probably produced after 1956.

Condition of Billboards
:
The “Lionel Trains”, “Shredded Wheat” and “Navy” seem to have a water stain on them. All others have some surface wear. 4 of the billboards are not completely flat but fit into the billboards nicely. An example is the “Wrigley’s Spearmint” billboard, see photo of it. All cards are cut. Most edges are good, some wear.
Please examine photos closely.
