This is a vinyl bag from the 1970s featuring the McLaren M23 F1 car. I don't know much about it, but "key." and a signature are printed on the bottom left. The size is approximately 40cm x 30cm x 4cm (depth), making it a convenient bag for carrying documents. Would be a great addition to a collection. I'm not sure of the market value, so I've set the price a bit high for now. I may lower the price or switch to an auction later. Please feel free to ask any questions or make requests in the comments.
