Hi Brian,

Thank you for contacting Mearto with your appraisal inquiry.
The signatures *look* authentic to me but it's next to impossible to authenticate signatures from photos; that said, I've given this the benefit of the doubt and assume the signatures are correct but my value is conditional on them being authenticated. If any/all of the signatures were determine to be spurrious, the value of this would be decorative, likely at/around $100.
Based on the photos and information provided, and subject to examination, this is:

Thure Thulstrup (American, 1848-1930),
"The Winning Run "How is it Umpire?" 1885
colored lithograph after earlier woodcut engraving
autographed by Mickey Mantle, Joe Demagio, and Ted Williams
sheet 10 by 14 inches, unframed.
CONDITION: appears to be in generally good condition
PROVENANCE: acquired at a storage auction
$400-600*
*represents a fair-market value for auction purposes; retail or asking price may vary.

Please let us know if you have additional items to appraise, and thank you again for using Mearto.
