Here’s an oddball card. This is a card from the Tuck ‘Smiles’ line, Series 169. But the back of the card has an ad for Butter Crust Bread rather than the standard Tuck reverse. I guess this bread company contracted with Tuck to offer their cards, maybe in a giveaway, with their logo on the back.
That's a real collectible,I've seen this happen a few times. Tuck had nothing to dow with Butter Crust, a distributor would have a pile of cards printed with the product logo. They'd just have a lot of cards printed over, maybe no two the same card. I've had them where a local politician would have a message done like this, the card face having nothing political about it.
