We tend to shy away from the word "rare" as much as humanly possible, but given the nature of our endeavors, the temptation to go there is almost constant. In this case it's mandatory, as this vintage baseball flag is precisely that. Dating to c.1937-1943, is a Kansas City Blues felt mini-pennant. A 1902 charter member of the Triple-A American association, the KC Blues came into the New York Yankees fold in 1936 and remained an affiliate of the Major League super-power through the 1954 season. In 1937 the Blues home field was re-named "Ruppert Stadium", after the Yankees owner Jacob Ruppert. In 1943 the name was changed again to "Blues Stadium", which makes the dating of this rare 9" pennant to c.1937-1943 a cinch. At left is an applique of the stadium's grandstands and at right is lettering that reads "Kansas City Blues Ruppert Stadium American Association". A couple of pinholes are noted near the tip and there's a bit of loose thread on the gold accent strip at the wide end, though this strip and the tassels remain securely attached. All graphics remain distinct and with deference to the described wear, this tough minor league stadium souvenir presents EX details.
