I believe my dad's best artwork was in the 60s, then again, I am a little biased for that era. Back then, some of his posters were originally on wood and then photographed like the Buffalo Springfield Last Time Around LP cover - some awesome stuff. I actually held that original Last Time Around piece - a 4'x4' piece of wood about 6" thick. There is so much artwork that I cannot possibly put it all here. Please contact me if you would like to see more.
