"The Monster" has a number of rarities that are well-known among collectors, the first tier of which include the "Big Four" of Wagner, Plank, Magie and Doyle.  Those four cards are enormous and well-chronicled cards that routinely make waves in the hobby for their record sale prices.  The next tier of rarities in the set includes this, the Ray Demmitt "St. Louis" variation, largely considered one of the six most difficult T206 to obtain.  

Demmitt was a journeyman outfielder who compiled a seven-year career with five different teams.  A member of the Highlanders, Demmitt was traded during the winter of 1909 to the St. Louis Browns for catcher Lou Criger.  When producing the baseball cards for the 1910 season, most of the ATC factory issues continued to depict Demmitt as a member of the Highlanders.  Of all the factory issues, only the Polar Bear issue made the change to depict Demmitt with his proper team.  This created a significant variation within the set.  The Demmitt/St. Louis variation is considered to be one of the key rarities within the hobby's most widely-collected prewar issue.  This example has been graded FR 1.5 by PSA due to overall wear, including some light creasing that breaks the surface of the card, and heavily-rounded corners.  A significant rarity, increasing in demand in recent months.
