Great story, Robot Man! I think it's awesome that so many of his books now form a big chunk of your SA collection. Hopefully, some of them will stay together indefinitely, but I guess the winds of time favor the scatter of entropy. Every cover you posted is a winner with me!!
I don't have any OO collections this expansive residing in my collection, but I have a few smaller ones - perhaps this will inspire me to put them back together before my kids get ahold of them and sell them off like hot potatoes?
One handful that comes to mind are a few dozen late 40''s and 50's books from a collection that I priced out for a friend of mine's dad way back in junior high. I can picture a lot of Atlas books, most of them westerns with characters like Black Rider and a few Fawcetts. I saw a master list in my teenage scribble within the past year or two. No high dollar books, but stuff he let me pick off at something like half of Overstreet (single digit, for sure). Battle #1 was among the ones I got, and also Black Rider #8 with the Stan the Man photo cover. I wish I had bought them all, but even back then I understood that would look like a conflict of interests, so I explained which ones were better than others and why.
