1949 Bowman - variation?

[scooter729]

Hey there,

I'm posting this for a friend who asked me, and I'm not too familiar with the set, so I'm hoping someone may be able to help.

Check the image on the first '49 Bowman Sam Zoldak NNOF (borrowed image off ebay). This is the version that is known for this card, with a distinctive light green background.



Now check the second image - this is his card. The background appears to be gray and not green. The rest of the image (jersey, hat, etc.) on the gray background appear to line up color-wise with the green background, so it's not just as if the color was light all-around on the card.



Is this a known variation? Printing error?

Any thoughts are appreciated - thanks!
Scott
