One great thing about being a kid in the 1960s was reading the ads in between the stories.
The "Comic Pack" had four 12-cent comics for 47 cents. Nearly always, there was a great comic like Superman or Flash on the top of the stack, while inside the pack were some losers like Binky or Young Love. Bleahh!
Then there were the house ads, like this one for the Second Superman Annual. I very seldom had the cash (a whole quarter) for one of these 80-Page-Giants when they were "new." But I caould afford to buy 'em second-hand at that downtown grocery-store/used-book-store, or swap for them with my friends.
