Thank you for submitting your item for appraisal. This appears to be a larger denim artwork by Ian Berry (*1984). The artist is relatively young and therefore none of his works of art have surfaced at auctions yet.
Based on the current "asking prices" and the fact that his self-promoting activities are in full swing, supported by favorable news and reports and that is style is very unique, the estimate is as listed above ( if authenticated by the artist himself).
