The QM has a post with a link to old toys. As a child of the 70’s I still have a big collection of Micronauts (including Baron Karza) , Battlestar Galactica action figures and vehicles and Giant Shogun Warrior robots. The shogun warriors were great because they shot all sorts of projectiles which we then tipped with sewing needles. I had Manzinger -his left hand fired rockets from his fingertips. Amazing enough I still have vision in both eyes.
Missing from the list was my favorite toy from the 70’s- Mobile Action Command or MAC. Its obvious to me that MAC had stopped testing for steriods around 1977. When MAC first came out they had normal (well, as normal as squared plastic action figure can be) physiques, but a couple of years into production they developed these enormous biceps and chests.
