Heinrich Hoffmann Rally Card No. 50 originally published in 1935, showing Hitler saluting in front of the bronze National Socialist Eagle on the Luitpoldhain.
Mailed from Postamt Nurnberg 2 on 13 September 1936.

Hoffmann Rally Card No. 50 franked with Sc 442-43 and mailed from Postamt Nurnberg 2 on 13 September 1936. It is of note, however, that these 1934 issues were invalid for postal use effective 31 December 1935. Not only that, the card has been canceled twice.
The double circle date stamp cancellation with the identifying letter “u” is somewhat indistinct, but it appears to be under the 12 Rpf value. In this variety, the divided shield has three shaded bars. The second cancellation, a strong 28-mm single circle date stamp with the identifying letter “b” is the variety with the divided shield (with two complete shaded bars) on the right.
