Hah! I was wondering whether it may have been from Harley! I had looked through a pile of high grade DCs he had purchased locally in 2005 and I couldn't afford all the ones that tempted me so the #121 (and a #123) were among the ones I passed upon. Really nice looking copies, but with an annoying touch of spine wear. I've not seen better copies since though....
The ones I've been posting in the Ten Cent thread are ones I've posted already in the appropriate threads in the past two years. If you look around, you'll find hundreds and hundreds more of my scans.
I did take care of my comics when I was a kid. I used to yell at my friends not to fold the covers over when they read my comics because doing that wrecked them!
Unfortunately, I ended up selling all my comics myself to a used book store in late 1965 because I'd moved onto other interests - Drag Cartoons, Creepy and Eerie magazines, monster models, slot cars and gas powered Cox airplanes to be precise. All the scans you see me posting are of comics I've rebought since 1979 or so.
Here though are a few writeups I've posted on the comics I read and collected as a kid:
