In my teens and into college I had a LOT of black T-shirts with aircraft on them, done in a distinctive style. The company that made them was Blackbird International. Then, one day, I couldn't find them anymore. And keep in mind this is pre-web, so no Google, etc. I had their mail order catalogs, but the number no longer worked, etc.
Well, I just found them again.
Looks like Airborn Flightware bought them out back then. From their website, they still have the 'classic' Blackbird designs I used to wear. Looks like they haven't been static, since they have newer planes like the F-35 now too.
