I had an Erector set, a set of Lincoln Logs, and Legos. I still had my Legos when I got married and both kids got some so now we have huge totes of Legos waiting for grandkids to appear! Erectors and logs all long gone.
One thing about the Erectors. Growing up in the '70's my sister and I had some action figures like GI Joe, but different. One guy's legs got broken off, so taking a queue from the Bionic Man TV show, I used Erector technology and built him new legs! LOL
