Walt Disney book-of-the-month club by Random House:
My grandmother (the good one) signed me up for this, and I received one of these books every month, from '74 - '76. I had the above 2 pictured (1975) as well as 22 others. I always looked forward to getting these in the mail back then. Mom still has them up in her attic, and I keep meaning to snag them, but I keep forgetting to take them, although I'm not quite sure what I'd do with them now....
