I sold 14 of my 15 boxes of comics today, a collection accumulated over about 50 years. I started by buying at the Dresher 7-11, which is long gone. I traded many books back and forth with some good friends, and with an older kid who lived across the street and used to trade me comics from an orange crate of books he’d stolen out of a locker at his school. (That detail never bothered me because I wasn’t the one who’d stolen them. And because children are sociopaths.)

I was a huge Avengers fan...
