To champion a mixed media painting/ drawing with an illegible signature is easy when it looks this good. Suggesting a high price however, is limited, as the painting/ drawing cannot currently be aligned with a specific artist's price structure.
Someone will buy, frame and love it and perhaps never know who made this artwork.
Marked Down from $150 to $95
"Unknown artist" is appropriate when a work of art is unsigned and a supported opinion about who made it is not available (on Savvy Collector).. "Attributed to" precedes the name of an artist when information suggests that it likely was made by that artist (on Savvy Collector).
