The Conly Studios league schedule cards are extremely rare 1888 National League schedules that feature an actual photo of Hall of Famer John Clarkson, the lettering underneath the image identical to that of the N338-2 Hess "Big League" issue, to the point that some feel the Hess issue may have been produced by Conly, or by the Boston print shop responsible for producing the schedule, Alfred Mudge & Son. The Conly pieces are extraordinarily rare, with only a handful of examples known to exist, all featuring Clarkson, each image affixed to a printed schedule.

Some cases exist where the photographic portion of the schedule has been trimmed away, leaving an image to resemble a card. Such is the case here, with Clarkson in a pose as if preparing to deliver a pitch. Clarkson's name is typeset within the photograph area, significantly askew to the point of being almost vertical. The Conly copyright information appears in the border area below the photo.  The photo quality remains excellent, with some minor creasing, chipping and staining evident here and there. It should be noted that the majority of the Conly schedule cards - all but one, in fact, feature a portrait of the Hall of Famer. This auction also includes the only known example of a second pose of Clarkson. This pose represents a third pose, one we have never seen before, extremely rare and desirable despite being trimmed from the schedule.  An extraordinary piece, the only known example featuring Clarkson in this pose.
