Europe and Overseas,Olympic Philately and Memorabilia - Day 2

1912 Gelber Hund airmail 1M on 10pfg brown red with inverted blue overprint and variety “Gelber Huna”, mint with a very light trace of a removed hinge. An extremely rare overprint variety, probably only 4 stamps per sheet show this variety and thus no more than 4 copies should exist (of which only two are said to be recorded); a major rarity of the German airmail stamps in very attractive condition, certificate M. Brettl 1983 mentions a minor corner bend (which is not visible to us). Michel lists normal invert €7'000 with 100% premium for the “Huna” variety = €14'000.
