THE WIDOW'S PIQUE is from strips printed in 1976 and condensed for this story. You can see all the strips (that I have) from that era, including this story at the DAILIES - 1976 collections.
GORDO REDUX Daily Collection Part One
These strips are from an unpublished collection called GORDO REDUX. (See GORDO BOOKS by Gus Arriola). Although undated, the style and context of the strips POSSIBLY puts Part One in late 1979 and Part Two in 1982. Some of the strips are found in the 1980s collection, which helps date them. Those strips are included in the DAILY collection. The rest are below.
