Hi Anthony,

Thank you for contacting Mearto with your appraisal inquiry.
Typically, publicity photos don't have much value unless they've been autographed; the inscription on the back of this looks like it's an inventory denotation or other internal writing and not Dangerfield's signature.
Based on the photos and information provided, and subject to examination, this is:

A vintage William Morris Agency promotional photo of Rodney Dangerfield
circa 1950s
black and white photo print
10 by 8 inches
CONDITION: warranted to be in excellent condition
PROVENANCE: acquired in an online auction
$ 10-15*
*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, or questions/concerns, and thank you again for using Mearto.
