Last copyright on paper is 1967 and based on design the roll is either that year or very early 1970's. Contact paper has great adhesion based on a small separate piece from the roll we tested. Unknown rolled out length but huge 3 1/4" diameter roll that does not appear to have a cut edge as it is super straight so likely a full manufactured roll for cut pieces. This is not the smaller household roll that are a fraction of this size. We would guess 50 yards though this is only a guess. 18" wide.
The bright colors on the roll show as spotted but they are solid and smooth and just a function of the photo processing limitations.
