Thank C2C! It appears that COMC has them as a stand alone set, not associated with any other product. I wonder how these were distributed? TCDB doesn't list them, as far as I can tell. Interesting to me that 3 of the 4 autos on the COMC site are the 3 players I'm missing for the 1998 Sports Illustrated auto set (Cruz Grieve, Konerko). Also interesting to me that there are versions of all 3 on COMC that are SN250, as the 1998 Sports Illustrated should be. I also find it interesting that PSA didn't identify the Konerko card that you added. The PSA population report for 1998 Sports Illustrated Autos shows 16 graded cards, but only the Brock and Robinson have been graded, none for Fingers or the 3 players listed above.
