Here is an unusual Wilson sample swatch book used by Wilson salesmen to sell uniforms to professional and local teams. Each page has a swatch of resplendent flannel in varying shades of gray. Measuring 3.75x5.75", the book contains 11 pages with six different grades and versions, and shows two swatches of flannel on each page. The cover has sewn raised lettering and "Wilson" logo. First one of it's kind that we've seen, displays some minor discoloration and wear.
