I have been spending my nights lately reading through my entire comic collection. It spans quite a number of issues and years. I didn't collect, for the most part, your typical titles though.
Of course I have X-Men and a smattering of Captain America but for the most part I was always drawn towards the more experimental titles that were around in the late 70's and early 80's.
Some were on the DC label, some on the Marvel but mostly Epic was my preferred reading choice. Dreadstar being the first of the collection. Of course Dark Horse was a great one as well bringing in artists like John Bolton on the mini series the Black Dragon.
Below are some scans of my favorite adds from the Marvel comics I have. This may be why, to some extent, I was never too keen on the mainstream comics on my youth. Never have liked commercials.
These are all from 1978.
