Looking for n300 or n162 ad pieces, oddities, etc...

There's a guy on ebay selling similar looking cards with blank backs and saying they are some sort of parallel set to the N162's that could only be redeemed through the mail. Has anyone ever heard of such a thing or have knowledge that these cards are legitimate and actually exist. Here's his response to my inquiry.

"ln 1888 Goodwin printed two sets of Champion Cigarette Cards, they consisted of 50 cards representing baseball, pedestrian, jockey, lawn tennis, etc. You could find them in Gypsy Queen & Old Judge tobacco pouches, these had Gypsy Queen & Old Judge writing on the base of the card & writing on the back. The other set (The one that l am selling) has the same picture on the front but no writing on the base or back. To purchase one of these you needed a coupon & then you could exchange it for a card that came from a Sports Card Album. The card l am selling is 125 years old, original, & 100% genuine. l am even prepared to give an undertaking that if the winning bidder can prove it is not 100% authentic, they can keep the card & get a full refund. But this wont happen because as mentioned this cigarette card is 100% authentic"
