Right here in the superstore. I think you can find vintage looking stuff most places. Here is some of what I found in the superstore...not sure if you would classify it all as vintage, but you get the idea.
I just found TONS of stuff at my local antique mall last week, I'd definitely check yours if you have any nearby. You never know what kind of stuff you will find at places like that, and they're always getting new stuff in.
