This listing is for a lot of 19 vintage architectural glass blocks I salvaged from an early 1900's building. I put them in storage intending to eventually incorporate them into a shower wall, but that was 35 years ago and I still haven't got around to it so they have to go. There are 17 squares measuring 5-3/4" X 3-/78" and two rounded over corners measuring the same. There is an edge chip on one of the squares and one of the corners as well, but I think they are still usable. There is also some grout in the channels from the previous installation. It comes off fairly easily with steel wool, but for most applications you would apply more grout in the same locations anyway. Selling as a lot for .00 or best offer, but sorry I will not part them out. Local pick up only in Whitefish, Montana.
