My POGO STICK !!! When I was 12 ... still love 'em, still snatch 'em away from kids when I see one, and "boing" to my hearts content !
Other favs were my microscope set when I was 10, and my human anatomy model ... (clear plastic model of a woman, had loose bones, organs, etc. you had to paint and fit into the correct places in the body, paint all the veins and arteries.. bones had to be connected to each other properly... and she even had a tiny fetus and maternity belly you could snap on if you wanted a preggy version).
Others were my woodburning set, my cinderella watch, and my Tiny Tears doll, and Ginny Doll . And of course my very first OWN transistor radio when I was 16 !
Soooo, now you can guess my age ! :chuckle
