I was just flipping through an anthology series in my collection called TIME TWISTERS reprinting early 1980's British material by guys like Alan Moore and Grant Morrison. It's pretty cool to see them developing their talent in stories with clever twists that are generally between 2 and 8 pages. Many of them, even at that early stage, quite clever.

"Quality Comics" was a late-1980's/early 1990's imprint of SQ Productions, who published one of my favorite underground/alternative comics.
HOT STUF' from 1974-1978, an anthology that had a lot of nice work by Buckler, Corben, Adams, Morrow, Barr, Colon and others.
SQ also produced a lot of beautiful portfolios of the late 1970's and 1980's, including some of my favorites by Wrightson, Kaluta, Chaykin, Adams and Fastner/Larson.

Another title I enjoyed from Quality/SQ was a brief title called TEX BENSON, a beautifully illustrated Flash Gordon parody by a guy named Chuck Roblin. SQ also published a nice TEX BENSON Portfolio.
