There is currently a No. 17 on Ebay,
They ususally sell for between $70 and $100. No 16 and 17 come up very often, about two or three times a month. I've been watching for Campagnolo catalogues for about 2 years, and that's the first #12 i've seen. #13 came up once before the copy last week that sold for $400.
I'd like to buy a No 17a (silver cover, folded with staple, not spiral binding if anyone would like to sell one.)

Art Yow asked: Is a Campy Catalog No.17 , or any of Campy's supplemental Catalogs of the same period of any value? I had seen a Catalog No.12 go for $1115 on e-Bay.
