Intricate Antique Marquetry Wood Inlay Floating Shelf, Venetian Scene

This antique floating shelf has incredibly intricate marquetry wood inlay. The scene looks Venetian. Signed "Hachem Hussein, 22-11-929." I can't find the provenance for this, but I purchased it from an antique store in Manhattan in 2000 for $300. I've never seen another like this. Width at widest: 29.5" Height: 16.5" Depth of shelves: the two lower ones are 5"; the one at the top is 1.5"
