Issued in 1911 as a premium for which a consumer of Pinkerton's tobacco products could redeem ten coupons, the T5 Pinkerton cabinets are "true" cabinets, consisting of a photograph affixed to a heavy cardboard mount. Like the N173 Old Judge cabinets, it is unknown how many subjects were actually produced. A complete checklist will likely never be developed, though early advertising for the promotion indicated that 376 different cabinets were initially available. Today, the T5 Pinkerton cabinets are among the most desirable baseball issues of the era.

This example, featuring Walter Blair, has been graded Authentic by SGC, as is the case with many Pinkertons due to the way that the photos are glued onto the mounts, with spots of glue on top and often loose at the bottom. It is an attractive display with some edge wear along the sides and surface abrasions at the top. The mount appears strong, with some mild toning on the reverse, but the photo presents well and has plenty of eye appeal.

SGC has only ever graded 2 total examples of this T5 Pinkerton Cabinet card, with only ONE receiving a higher grade than the Authentic offered here of Walter Blair.
