Scott No. 426 in a strip of 3 on a postally used cover cancelled at Mannheim, 14 August 1936. Unlike the cover dated 6 May 1936, it has no backstanip. Note the handwritten “Mit Luftschiff Hindenburg” and that the handstamped pink cachet differs significantly from the steel die red cachet used on the 6 May 1936 cover.

Scott No. 426 in a strip of 6 affixed to the back of this Hindenburg cover was cancelled at Mannheim, 14 August 1936. Not only is this an unusual way of franking, the total postage of 225 pfennig is almost twice the rate for a Hindenburg posting.
