(Universal, 1936) Exceedingly rare and possibly unique color 14 x 22 window card for the 1936 film The Invisible Ray, directed by Lambert Hillyer and starring Boris Karloff and Bela Lugosi. The upper imprint area is filled out in pencil with the showing information, reading: “Tues, Wed / June 9, 10.” Attractively double-matted to an overall size of 18 x 26, with a mat opening of 13.25 x 21. Some scattered creasing and a few small retouched and repaired areas, otherwise fine condition. The film cast Karloff as the scientist Dr. Janos Rukh, whose touch turns deadly after he is exposed to the radiation of a powerful new element called Radium X. Lugosi played Dr. Felix Benet, who develops a serum to hold the effect at bay. The consignor acquired this window card at the Morris Everett auction held at the 1994 Cinevent classic film convention in Ohio. Research and consultation with experienced collectors have yielded no other examples of window cards for this film, while one-sheets, inserts, and lobby cards can be found; this window card is quite possibly the only example of its kind. A true rarity that features the most important sci-fi horror stars of the era.
