Dear Alan,

Thank you for the additional images and your patience. Sadly regarding technical problems, the new images and messages were not displayed. I apologize for the delay.
The presented object is a mixed media artwork with the measurements of 36" x 18". This artwork is a collage made out of parts of typewriters fixed on a white painted board. The artwork is dated 1957 and signed by Henry Newman. The American artist Henry Newman was active in the second half of the 20th century and made many collages.
This piece is in good condition and there are no serious damages visible.
An estimation would be between 250 to 500 USD.
This estimation is based on actual recent past recorded auction sales of comparables. Retail "asking prices" can be higher and vary.

With kind regards,
Georg
