The last surviving cast member from the roster of classic Universal Monsters, Ricou Browning performed the underwater sequences in all three Gill-man films; the iconic Creature from the Black Lagoon (1954) as well its two sequels; Revenge of the Creature (1955) and The Creature Walks Among Us (1956). This caricature sketch of the Gill-man is hand-drawn and hand-signed by Browning and is certified authentic by CGC as part of their special Signature Series. With CGC’s Signature Series, a certified witness actually observes the signing/sketching and then immediately takes possession of the collectible so there is no chance for the real autograph/sketch being replaced or substituted. The sketch is drawn on board measuring approximately 6 3/4 by 10 1/2 inches.
