I made a simple display stand for every video game cartridge type I own
I use to sell games on eBay a long time ago and I still have quite the collection. So I made these display stands for my games. Would've killed to have these back when I was selling them!
If anyone doubts OP's nerd cred, that appears to be a Sony Playstation 3D Display in the background, there. That is definitely a niche piece of gaming history.
Fun story about it. When I bought it I was selling games and was buying from a guy who had a tub full of Skylander figures and games.
Bought it for the price of the games, made a profit, kept the TV for myself since it was so much better than anything I had before. And I didn't know what to do with the skylanders. Apparently they had value since a family member was able to offload them all.
