This is a chusen-dye tenugui (Japanese hand towel) distributed in the late Showa 40s to early 50s (around the late 1960s to early 1970s) by Cadillac/Buick authorized dealers for their "GMC Festival." I think it's probably a rare item. The color is closest in the fourth photo. The design is very Showa-era, featuring a Cadillac DeVille (Fleetwood series), which was iconic in Japan at the time, along with fireworks, paper lanterns, and scenes of families. Size: Approximately 35 x 60 cm. There are stains and some color fading. Please check the photos. It would look great framed.
