1.5x2.625". The 1910 Old Mill T210 complete set consists of 640 cards. The T210 is unique for a number of reasons. For example, the total complement makes it the largest 20th century tobacco-issued baseball series. Furthermore, it is comprised of eight different series, each one representing a different minor league. The set is immediately identifiable due to its distinctive red borders that surround a sepia likeness of the ballplayer; his surname and team are noted in black print at the bottom. Card backs include identification of the series number and Old Mill Cigarettes brand name.

Irvine was a Minor League baseball player for the Richmond team.
