davidcyclebackYou don't own a Topps, T206 or Old Judge's design/image by posting an example you own on your website. The card's graphics are not yours to own.
If an eBay seller is deceptively using the image of a card he doesn't own, that would be considered deceptive advertising-- and eBay has pulled auctions due to that.
There is much copyright protected images on eBay, so it is incorrect to say anything posted on a website is public domain. One could get into trouble if he worked under that belief.
Whether it is ethical or good manners to steal someone's Peck & Snyder image is a legitimate discussion, but likely will have little to do with copyright issues.
