I started reading Richie Rich, Casper and Walt Disney comics back in the 1970's. I also had over 100 Archie digests. I don't recall the exact moment I read my first comic, but I do remember going to the corner drug store a couple blocks away and buying comics. I still have the comics, but threw out the Archie digests just last year. Here are some recent pictures of the Richie Rich books. These books currently fill up one short box.
I eventually outgrew the Richie Rich and Archie, but I continued reading Uncle Scrooge - loved all of the stories and adventures that they went on!
