Many misapprehend the rarity of Piedmont Factory 42 backs, given Piedmont's reputation as one of T206's common brands. Factory 42 (named in the footer text) ranks #12 in overall challenge, according to T206Resource.com, a similar scarcity to Carolina Brights and American Beauty. This puts any card with such a back in rarified air when offered for sale and of particular appeal to brand collectors.

This SGC POOR 1 features a Factory 42 back and shows the personable portrait for Giants southpaw Hooks Wiltse, who won 136 games and posted a sub-3 ERA for that club before jumping to the Players League for a final MLB season in 1914. About 1% of graded cards are known with this Factory 42 back, so while its technical grade reflects surface wear and rounded corners, the acceptable image quality and back scarcity will no doubt drive significant collector interest.
