GRUNNNT! URGGGG! BOOGLE!

This is a grisly little tale called "Fiends From the Crypt" from Farrell's FANTASTIC FEARS #8 (July 1953). It concerns a group of creatures called The Green Horde and they don't like being swindled by a greedy thief. The story--by an unknown writer and artist--does not end well.

SMUR-DA!

DEATH BY JELLY (PEANUT BUTTER NOT INCLUDED)

This one's about as weird as they get. A (yes) mad scientist concocts a serum that he injects into a blob of protoplasm and the thing morphs into a humanoid monster that -- what else? -- goes on a killing rampage.

Nice artwork by the team of Bob Powell (pencils) and Howard Nostrand and Marty Epp (inks).

"Jelly Death" from CHAMBER OF CHILLS #6 (March 1952).

AL FELDSTEIN BEFORE E.C.

Before Al Feldstein became an influential workhorse at Bill Gaines' EC Comics and horror comics in general, he plied his trade at the American Comics Group (aka ACG). Feldstein scripted and illustrated this story, "The Creekmore Curse" for ADVENTURES INTO THE UNKNOWN #3 (February-March 1949) featuring a creepy character by the name of Dr. Gaunt and his demonic disciples. Feldstein started working at EC in 1948, but he was still freelancing at the time.
