Back in 1996 when Signature Rookies ended, their remaining card stock was bought by a company called MR Fulfillment (located somewhere in Vermont). They sold many of the leftovers - signed & unsigned - sealed or resealed packs & boxes - singles & sets - through various mail-order offers. Several cards were reissued with "special" or "promo" runs of varying numbers, depending on their sales gimmick. I don't think many of these are listable on this site, due to their "secondary market" status, especially the unsigned & non-serial numbered cards like that one.
