This must have been from a Nascar event held in Japan in the Spring of 1992. It's in very good condition with one flaw - on the back of one sleeve there's a small (1/8" x 1/4") white spot that looks sort of like glue or sugar which I really think will wash out (I haven't laundered this). Can't read the label very well; think it says Marnky  Kyoto  Tokyo. I'm not sure how to measure it, but I'm positive it's no larger than a mens medium. It measures 23" across the back from side seam to side seam; 49" across the back from the bottom of one sleeve to the bottom of the other; 34 3/4" from the top of the neck to the bottom of the shirt/jacket measured down the middle of the back.
