Vintage 60s 70s NBA CONVERSE Chuck Taylor All Star Blue Label RARE USA Japan 73

Insanely rare pair of NBA chucks. Dated 1973 made in Japan. Not sure on the story of these but I can’t find any info about them online. They are size 7 but run a bit large. Please look at the measurements of the outsole. Shoes are dried out and stiff. Would not recommend for heavy wear. Can be worn, but if worn excessively and they will crumble and fall apart. These are old shoes, not really meant for wear. Other than the dusty smell and dry sole, these are great! Thanks for looking!
