Vintage navy blue bag with red vinyl straps

This vintage big is in mint condition. It looks like it could be from the 1970s, but I am not sure. It is navy blue with red vinyl straps. The straps are curled due to inactivity. The vinyl straps have no cracking and are riveted onto the blue material. The interior of the bag is clean and has a black thin board that goes across that is clean with no scratches. This bag has not been used. I took measurements of the bag and most of the bottom corners are in excellent shape also. I noticed there is a corner with a small crack in the red vinyl. #vintage #bag #vinyl #70s
