Dear Dan,

Thank you for your help and patience. My sincere apologies for the delay with the appraisal.

The presented object appears to be a charcoal drawing on paper with 17 x 14
inches measurements. The drawing depicts different motifs in a realistic style. The artist Dan D Gatson is talented but sadly not established in the secondary art market. That means an estimation for the secondary art market is related to pieces in auctions.
Comparable objects were recently offered and sold on the international auction market.
This piece is in good condition and no severe damage is visible in the images provided.
A fair market estimation would be between 10 to 40 USD each.
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,
Gregory
