Dear Andrew,

Thank you for contacting Mearto with your appraisal inquiry. My sincere apologies for the delay with the appraisal.

The presented object appears to be a painting made in oil or acrylic paint on canvas with the measurements of 2 1/2' x 3'. The painting depicts a portrait of a Native American chief and has the title "Hollowhorn Bear". It is signed by H. W. Wyman and dated 1904. Sadly no additional information is given in reference books and databases.
Comparable objects were recently not offered and sold on the international auction market.
This piece is in good condition and there is no serious damage visible in the images provided.
A fair market estimation would be between 100 to 200 USD.
This estimate is based on actual recent past recorded auction sales of comparable items. Retail "asking prices" can be higher and may vary.

With kind regards,
George
