Cover produced specially for the Museum of British Road Transport Coventry to raise funds for the restoration of a 1920's Maudslay bus.
Se-tenant strip of Royal Mail bus stamps cancelled with 1935 Leyland Cub on first day of issue. Cover shows bus before and after restoration.
Covers carried to Bletchley Park by the museum's 1944 Daimler. Issue sold out so no idea when next one will be along!
