Monochromatic print of Canada geese in flight attributed to Richard Bishop

This item appears to be an intaglio-style print, such as an etching or engraving, depicting three Canada geese in flight against a light, atmospheric background. The composition shows the birds in various dynamic postures, possibly descending or landing. The artwork bears a pencil signature in the upper left margin reading 'Richard E Bishop' and a pencil inscription in the upper right margin reading 'Federal Duck Stamp Design'. Additionally, there is a visible plate mark or copyright line in the upper left corner of the image area that appears to read 'Richard E Bishop ©'. The owner identifies this as an original ink drawing from 1936 used for the third Federal Duck Stamp; however, the visual characteristics, such as the plate indentations and line quality, are more consistent with a print or an etching. Without physical inspection, it is impossible to verify if this is an original period print, an artist's proof, or a later reproduction. The work is framed with a light-colored mat and a dark thin frame. The condition appears good from the photo, showing a clear impression, though some minor discoloration or light toning consistent with aged paper may be present. The identification remains a hypothesis pending in-person verification by a specialist.

Based on my examination of the provided images, this work bears a signature and inscriptions consistent with the hand of Richard E. Bishop, specifically referencing the 1936 Federal Duck Stamp design. Per the user's submission, this is attributed as the original ink drawing; however, the presence of a plate mark and the character of the lines suggest the piece may be an etching or a drypoint print from the period. I cannot verify from a photo whether this is a unique work on paper, a limited artist's proof, or a later reproduction. The estimate of $1,500 to $3,500 assumes the hypothesis that this is a period-appropriate print or proof personally handled and signed by the artist. If physical inspection by a specialist were to determine this is indeed a unique preparatory ink drawing, the value could significantly exceed this range. Conversely, if it is found to be a photomechanical reproduction or a later restrike, the value would likely drop below $100. Factors such as the light toning and framing appear consistent with mid-20th-century origins, but scientific testing of the paper and ink, along with a review of provenance documentation, would be required to establish its history. The market for early federal duck stamp-related art remains specialized but steady among wildlife art collectors. A physical inspection is essential to confirm the medium and the veracity of the signature before a final valuation can be assigned.
