💀2/$30 set of 2 Vintage Charlie Brown Comic

A Fawcett Crest book from 1981 and 1979. In really good condition with a few marks up at the top right ( included in the picture ) and the blue book the front page lifts off halfway while the other pages are ok . The pages have yellowed a bit with age . It’s approx 4.5”x7” and about .5” thick . Not sure how many pages to be exact .
