Uncommon vintage inscribed blue fountain pen signature on a 4x6-inch light green autograph album page, acquired in-person in the early 1940s. In fine condition for its age, with some light surface creases passing through the writing in one spot. Great, creepy character actor Martin Kosleck, whose icy demeanor and piercing stare made him the ideal Nazi official, spy or psychopath, was memorable in the horror and sci-fi films Alraune (1930), The Mummy's Curse (1944), The Frozen Ghost (1945), House of Horrors (1946), She-Wolf of London (1946), The Flesh Eaters (1964), and Agent of H.A.R.M. (1966).
