What is this Mantle & Maris Photo?

[paul]

This photo of Mantle & Maris with facsimile signatures was recently on ebay but didn't sell. Any ideas what it is or who issued it? Thanks.

Austin Mike first alerted me to this issue. I have one as does he. He may be able to shed more light regarding the origin than I am. My understanding is that it is a career contemporary piece--likely the 60s given its Mantle and Maris. I believe it was inserted in a package--hence the rounded upper corners--but don't know what package. It's not a particularly rare piece but it is cool. I think they sell around $30-40, so, with some time and searching, you should be able to get a reasonably priced one in good condition.

I don't know much about the photo either. This site,

http://mickeymantle7.net/mantle-premiums-2/

lists it as an unknown premium. They also have the same photo with four square corners shown as a crew sock premium. As Chris said, these rounded corner photos seem to be plentiful and are frequently on eBay. I've not seen the square cornered one on eBay.
