First one i remember reading was in the barber shop X-Men #25, decades later i read #26 to find out what happened.
First one i remember buying Justice League of America #100 & 101 they had the JLA/JSA teamup looking for the 7 Soldiers of Victory. Mom ripped them up and when i tried to buy them again she sent me back in the store to swap them for something else. i got a Partridge Family and a Bobby Sherman comics which dissappeared real soon afterward.
The next comic i bought started my long time collection Green Lantern/Green Arrow 121 with ringless GL falling out of a plane with Arrow looking out the open hatch. still love that cover.
