I am pretty sure these are from the 50's. Set needs some work. They got put in storage before I was able to get better photos. Fabric is an embossed vinyl, sort of like an old school heavy duty tablecloth. It looks like they started to re-do them in a different color or perhaps they bought mismatched pieces. There are a number of small tears which are mainly at the seams. Perhaps they could be resewn in just the seam areas. They are a little dusty and musty from storage. A leg on the back of the sofa was repaired, it works fine and is only noticeable if you turn it upside down. Set needs some cleaning up but a unique, interesting look.
I have a number of Danish / Mid Century modern pieces listed if you want to look at the " more ads by this seller" link in this listing.
Set is located in Northern RI. I'm about 20 minutes from Providence and a little over an hour from Hartford or Boston.
