Boris von Trappe
Boris von Trappe is the author of that indispensible travel guide, Mein Abenteuer in Überwald (My Adventures in Überwald), possibly "Mein Abenteuer..." for short. There may well be a picture of him on p138 of Mrs Bradshaw's Handbook, in a group iconograph of hikers just about to set off out of the current rail terminus at Ohulan Cutash for a walk into Uberwald.
