A Babe Ruth signed Photo is worth about $3,500.- $5,000. Price will vary based on condition, and the type of authenticity that accompanies the signature. Photo composition, appeal, how well the photo displays the signature, the type of ink used, and how it stands out in contrast to the photograph will also effect the value. Larger photos will sell for more.
The signature should be bold, strong, and stand out in contrast to the photo. A weak, and faded signature will sell for less. Most autographs in Ruth's day were signed with a fountain pen.
In a few recent auctions a signed 3 x 5 photo sold for $5,377.50. a large 17 x 21 fountain pen signed photo with inscription sold for $23,900.
