I picked this up yesterday, among several other vintage items, from a small shop that supports a local charity. It's not really "minty" looking, but I believe it probably predates the Criterium listed as the earliest one, at VeloBase. I went there looking for info, but it looks like I might have to provide it, instead, LOL. In other words, VeloBase guys, feel free to use these pics, if you want, all other 3rd party folks, please respect Bike Forums' rules & practices.
