We have a Floral Wallpaper Partial Roll Vintage item.  It is from between the 1960's - 1980's and measures about 26 1/2" in W, I'm not certain of the length.  The outer edge of the roll measures about 1 5/8" with about 1" being the cardboard and hollow inside roll.  I would estimate there may be between 3 - 5 yards on this.  It is fairly heavy with the back feeling more like a fabric.  There is some discoloration on the backing but it doesn't seem to carry through to the front.  It is unpasted.  The large gold flower is about 4" across the center and there is a pattern repeat of about 18".
