70s Kitsch Nautical Ship Navigation Map Fabric Red with backing 2 yards x 42"

Vintage 1970 Kitsch Nautical Fabric - Red Featured is one of those great fabrics from the 1970s that hit around the Bicentennial period with an 18th century theme, this one nautical. Measures 42" wide and 72" long. It has some sort of backing. (see photos) This was fabric my grandmother had, but I don't know anything about fabric. I don't see a brand or anything on the edge. It's been sitting in a room in her home for as long as I can remember.
