Breathless Homicidal Slime Mutants sucks.. the artists are not properly credited..Plus, many have nothing to do with "Slime Mutants." Many are historical or best sellers..NOT sci fi. This does not take that much effort. My father, Robert Maguire, was not credited for the 3 cover illustrations he did in that book..one even had the wrong artist. (He did not do the on that was in the index..on pg. 65..It is very nice and deserves the proper credit.)
He did The Golden Blade (the 2 page spread..) and Swords for Charlemagne (another worthy of 2 pages) AND.. Maguire did Creeps by Night. Why not do proper research?
Weren't any of the books signed or credited??? You could have also contacted Graham Holroyd, or authors of other books on this subject, like Gary Lovisi.. Lynn Munroe.. etc... Very sloppy work. Just trying to make a buck out of other peole's work.. as usual these days.
