Hi Christo,

Thank you for contacting Mearto with your appraisal inquiry.
I've found a few versions of this painting that have been sold previously and - in the closeup photo of the signature, can see that this is a canvas print, a way to reproduce the same image over and over by projecting acrylic or oil paint onto canvas.
These have a more decorative value than historic, typically bringing about CAD $75-100.
Based on the photos and information provided, and subject to examination, this is:

G. Selurtis (European, 20th Century)
Untitled portrait of a man in a tavern
canvas print
75 by 55cm (29-1/2 by 21-5/8 inches)
CONDITION: This painting appears to be in good condition with no tears
PROVENANCE: Inherited
$ / £ / € VALUE*
*represents a fair-market value for auction purposes; retail or asking price may vary.

Please let us know if you have additional items to appraise, or questions/concerns, and thank you again for using Mearto.
