There are a ton of names I have seen vintage SW stuff for sale at over the years (nothing recent, but I haven't looked too much) and some at shows that the names I would never have guessed to see SW stuff.
I am from NJ, and I know the names should be in line with what you will see:
- Monster-Mania Show or Monster-Mania Con
- Retro Toy Con or Retro Toy Show
- Sci-Fi/Horror Con or Sci-Fi/Horror Show
- The Horror Show
- Toy & Collectibles Show
- Toy Show or Toy Con
- Comic Show or Comic Con (not the big boys like in SD or NYC, just locals)
Most of those were hosted in either hotels near a major airport or local fire-halls, VFW or American Legion Posts.
If I think about more, I will post 'em. The shows above I have gone to were in NJ or PA or lower upstate NY or lower CT in the past but that was well over 15+ years ago so I don't know if any still run. I loved the Monster ones BTW! Weird people... weirder than Sci-Fi fans or Trekkies!
About 20 minutes from my house they do a Toy & Collectibles Show in Wayne, NJ pretty much monthly but I haven't gone since I got the collecting bug again, but back in the day there weren't any deals really... just average prices since they all knew what they had... but I am better at haggling now and more focused and plan on attending the next one on June 2nd so who knows.
