2.25 x 2" (dia.)

Lot includes a scarce, complete collection of all five 1910-1914 consecutive year antique embossed brass Massachusetts motorcycle registration tags (these were used instead of license plates in the state during these early years) w/ loop at top for attaching leather strap for using as watch fob (the fobs were required to be carried by operators while riding the bike). These are quite nice overall, w/ expected darkened patina and minor wear from use.
