This post all started when I came across this image:
Growing up in the 70s, my mom had quite the collection of Fisher Price toys. She had "Little People". A few of the sets she kept and let me play with, but the real mecca was at Granny's house. My grandmother had kept her daughters' Fisher Price toys and I LOVED them. Here are some of the sets via google image search. Here we have a hospital, camper, castle, house, carousel, airplane, schoolhouse/playground, and my favorite Little People- the girl in blue. Heck, I would still play with these even now.
