Ditto for me. This is what got me into birds in the first place. They
also had a great series on dinosaurs. The cereal companies also got
into the game. I forget which company did the wall poster with the
cards by RTP (came out at the same time as the 2nd (?) edition of RTPs
field guide in the 60s) which you stuck on. That one is still in my
parent's attic. All eastern N.A. birds but very well done with a
picture of an adult bird and the eggs on one side and a write-up on the
back. Should get that one down from the attic...
