A 4-time All Star, speed demon George Case led the league in stolen bases for 5 straight years from 1939 to 1943. He ranks near the all-time Top 100 with 349 career thefts, and would've swiped plenty more were it not for an injury-induced early retirement at age 31. Case only wore uniform number "10" in 1941, which dates this grey-flannel beauty featuring "GW Case" chain-stitched inside the collar above a picture-perfect Spalding tag. The rear inside tail also carries a square size "42" label above the chain-stitched year "41".

Authenticator Phil Wood's LOA provides the following condition report and conclusion: "A 2.5 x 4 inch swatch of gray flannel has been excised from the lower right rear shirttail, a piece of fabric likely used to patch a pair of pants, a feature frequently seen in uniforms of similar vintage. Beyond that flaw, the shirt overall is in VG-EX condition, with all original lettering and still fairly heavy flannel...Pre-war Washington uniforms are far from common, and this one, from a particularly notable player, is all original and, in my expert opinion, 100% authentic."

Accompanied by a style-matched pair of pants worn by Nats teammate Bill Zuber, who won 6 games on the mound that year. The well-preserved pants feature a Spalding size-40 label and chain-stitched "W Zuber" tag. It's noteworthy to mention that the Nationals began donating uniforms to the Orioles after their Baltimore ballpark burned down in 1944, so early-1940s Washington garments remain quite few and far between.
