building spaceship models. I have no idea if kids today even still build model kits, but when I was growing up, it was both a frustrating and rewarding way to add to my burgeoning sci-fi memorabilia collection.
Here's a comic book ad from 1980 featuring the Battlestar Galactica and Buck Rogers model kits from Monogram. Presumably, the TV revival of Galactica: 1980 encouraged Monogram to try and move some unsold Battlestar Galactica overstock from a couple years before alongside the newer Rogers kits.
