Here are the Bascal Aluminum cups that I found. I really like these cups but the develop heavy condensation when you put cold drinks in them which kind of a downside and they also get pretty cold when there is a cold drink in them. With these 8 Bascal Cups My collection of them is not up to 19. I will have to post the other ones another day because I have a bunch of other colors. These are just the ones I found in my grandmas barn.
Here are the really unusual aluminum cups. I've never seen these before. I really like them too! I would definitely prefer using these over the Bascal because these have handles on them so that the condensation wouldn't be too much of a problem. I think these things are fantastic! They are made by Emson-Ware and are seemingly uncommon. I love them! :D
