Wow, I didn't realize Kallis was still alive. He designed so many iconic sci-fi and horror posters of the 1950s, such as Creature from the Black Lagoon, Invasion of the Saucer-Men, Not of This Earth, Attack of the Crab Monsters, The Brain Eaters, The Amazing Colossal Man, The She-Creature and countless others. His work is sometimes confused with that of Reynold Brown (the very famous one-sheet for Creature from the Black Lagoon has variously been attributed to both men, and there's still a degree of controversy as to who actually designed it). I probably own more movie posters graced with the work of those 2 artists than any other illustrator in my collection.
What a legacy Albert Kallis leaves behind...
