A.O.F.B. Stamps
Bert produced A.O.F.B. stamps. They were not legal postage stamps but were for sealing envelopes and correspondence. They were priced a 2/- 6d for a book of 60.
The stamps here are from samples sent to Vats. They were in strips of 3 advertising the hospital cots they were intended to raise funds for. The strip is down the left hand side, a close up of the ad and a stamp on the right.
