Vintage medium weight cotton duck fabric, not weatherproof, but originally intended for flags, banners, sunshade awnings etc.. It's all 30" wide, selvage to selvage.
This is unused never laundered fabric left from a series of 1950s shop displays and windows, in vibrant red, royal blue, deep yellow and gold. It's been in storage in a back room or closet for 60+ years, and does have some dust and surface soil to the outside wraps, though the colors are excellent, with no fading at all.
The red is 5 1/2 yards in one piece, the royal blue 15 1/2" yards (all one piece, some light chalk marks to the edge which rub right off).
The lighter colored gold fabric is 11 yards in one piece, and the deeper gold is one piece 4 1/2 yards long (this last piece has some chalk marks, too).
