I have 4 cases of 11 each from a local restaurant that bought them in the 70s and never used them. There are 3 sealed cases, and one opened. I am selling by the piece, buy 1, or as many as you like. If you want a quantity, feel free to make a fair offer. The cardboard is brittle from age, but have no water damage. I do not have any backs, only the seats. These are just so cool. The chances for finding a back to match, is slim at best, but if you could use them for a regular stool, or use a contrasting back, or????????? The seats are beautiful and vibrant with contrasting lines as shown. Well made, no junk.
