Czech Republic - Historical Means of Transportation

The stamps on this cover are from the Czech Republic's "Historical Means of Transportation" series and they commemorate some rather unique Czech designed vehicles. The Čechie 33 - Böhmerland is a motorcycle that can seat 3 people. And the Tatra 13/30 is a rail car that had the ability to rotate itself 180 degrees without leaving the railway tracks so it could be driven in both directions on the same track.
