Dear Mike,

Thank you for the additional images and your patience. The apprised object is a painting made in oil on canvas with the measurements of 21 x 18 inches. It depicts a city view on high buildings. It is painted in an expressive cubist style. There is no signature visible so sadly the artist remains not identified. Probably this painting was made in the middle of the 20th century.
This piece is in good condition and there are no serious damages visible.
An estimation would be between 200 to 300 USD.
This estimation is based on actual recent past recorded auction sales of comparables. Retail "asking prices" can be higher and vary.

With best regards,
Georg
