I can tell you that the 1937 yearbook only complains about Germany's treatment of JW's.
It did mention, however, the letter sent to Hitler by JW's from around the world. It did NOT mention, however:
1) the letter infuriated Hitler so much he set out to kill JW's (by their own admission they had only been arrested before) and this letter resulted in the death of 1000 JW's.
2) it's contents. "Stop persecuting JW's, or God will kill you and your Nazi Party". Of course, God did NEITHER...
