In 1979, GLJ toys (one of my favourite obscure toy companies from the era) did what a lot of toy makers did and grabbed a piece of Battlestar Galactica in the hopes it was the next Star Wars.
Their specialty was inflatable toys, even vehicles for the action figures which is just awesome.
It wasn't quite the bonanza they were looking for and I'm not sure half these inflatable toys ever got made. It's a fun trip nonetheless, check out the 1979 GLJ BattleStar Galactica Catalog here.
