These are awesome vintage Russell Athletic gold tag 70s era youth baseball medium white/green 3/4 sleeve raglan t-shirts. We found these as part of a collection we found at a sporting goods store that had closed down in the early 90s. This is made in the USA of a 70/30 cotton/polyester blend. Measurements are below. The measurements are close to a vintage adult xs size. Please see pictures for details and feel free to ask any questions prior to purchasing.
