As far as I can tell, the entire output of McQueeny consisted of 5 issues: Curly Kayoe Comics 1 & 2, El Bombo Comics 1, Spark Man Comics 1, and Snappy Comics 1 (as by Cima). It looks as if McQueeny was subsumed into United Features just before UF quit publishing comics. Both McQueeny and UF were distributed by American News Company which folded in 1957. To quote Wikipedia,
"The company's abrupt 1957 demise caused a huge shakeup in the publishing industry, forcing many magazine, comic book, and paperback publishers out of business."
