Collecting a "back run" of a specific player is one of the more popular collecting challenges in the prewar arena. Once virtually exclusive to T206 collecting back runs have migrated to the E-card world as collectors have learned how challenging the assmbly of a complete back run of caramel cards can be. Such is the case with Philadelphia first baseman Harry Davis. His horizontal card featured in the E92 and E101 issues can also be found in the tough E105 Mello-Mint issue. Broadening further outside the E-card realm the pose is also found in the impossible D355 Niagara Baking set as well as the T216 Kotton Mino and Virginia Extra issue. Staying within the caramel world does not however reduce the challenge dramatically. Presented here is an astonishing grouping of Davis cards each extraordinarily difficult in its own right. Included in the group are the following: 1) E92 Dockman & Sons Harry Davis PSA NM 7: Stunning high-grade example with razor-sharp corners and extraordinarily strong centering a faint print line keeping the card from attaining a higher grade. With PSA having graded 33 examples of the Dockman & Sons Harry Davis just one has achieved the NM level with a scant one example grading higher. 2) E92 Nadja Caramels Harry Davis PSA EX-MT 6: Another beauty this one the only E92 Nadja Davis to have been graded by PSA. While SGC has graded seven additional none of achieved a grade as high as this. 3) E92 Croft's Candy Harry Davis (Blue Back) PSA VG-EX 4: Beautiful sharp card with the extremely rare Croft's Candy blue back. Presenting well for the grade the rare blue-printed Croft's Candy logo on the reverse is sharp dark and clean one of the finest we have seen. 4) E92 Croft's Candy Harry Davis (Red Back) SGC EX 60: Exceedingly rare even more so than the blue backed Croft's Candy cards one of the toughest of all the caramel issues. Graded EX 60 by SGC the technical grade is irrelevant as this is likely the only example known. This card sold for nearly $1 800 by itself at auction three years ago. An extraordinary find. A spectacular grouping of four very difficult cards of Harry Davis including a high-grade E92 Dockman the highest-graded E92 Nadja and rare Croft's Candy Blue and Red Backs. Four cards total.
