Hi Victoria,

Thank you for contacting Mearto with your appraisal inquiry.
The fact that this poster was mounted directly onto a paneled oak backing - which has subsequently contracted/expanded and has separations that has split the poster - detracts from its value. The same poster - framed and intact - typically brings about $300 when sold at auction
Based on the photos and information provided, and subject to examination, this is:

A vintage Harvard Brewing Company advertising poster
"The Promised Rose", 1974
after Martin Kavel
mounted to oak paneling
36 by 24 inches
CONDITION: Affixed directly to oak boards, which have separated. Additionally, this has faded and has sustained some losses throughout.
PROVENANCE: Inherited
$ 100-150*
*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.
