Well I'd say quite a while ago, off the top of my head....but I don't want to guess what ERA, in case I'm wrong...but I've seen bigger one similar that were quite Vintage, so I'm guessing these are also...personality, I think they are kind of cool as well....different, eye catching, attractive, and great for love one's pictures you can put just about any where...but again...that is just my 2 cents.....:)
