Now Designs San Francisco Levis backpack

Vintage Levi denim backpack with red straps. Roughly 14 wide x 16 tall. It has the old style 501 xx patch on the front with the double horses. Vintage from the 1970s. There is some staining on the straps so please examine my photos carefully. It was made by Now! Designs San Francisco. It does still have a tag but it is worn. The interior of the bag is in great shape. The outside is in good condition. It used to belong to my mother and i remember it full of beach towels and water bottles in the summer when i was a child.
