Full disclosure of a sort: the SGC population report lists Stanage as both #168 and #170 in the D350-1 set, which is an oddity of the original naming, and this is the latter card, the other featuring a "still" pose.  Either way, this is the only example in the SGC database of card #170 in the 1916 Standard Biscuit set. The good news is that it looks pretty nice for the grade, noting the long horizontal crease running through the player's legs. The set is related to M101-5, sharing many subjects,  and indeed, an incorrect penciling indicates this at the top of the reverse.
