This shelf seems like it was part of another piece. It looks like maple, and it has a drawer that slides both ways through the piece. It seems like a deco piece but I am not sure. It measures 28 inches high by 10 inches deep by 22 inches wide.
Thank you for contacting Mearto with your appraisal inquiry.
This is probably more MidCentury Modern than Art Deco, though there were pieces made in the Art Deco period that had this shape, probably a bit more ornately decorated than yours. I think the wood is pine, not maple, but that doesn't matter so much in the value overall.
Are there any names or labels on this (perhaps inside the drawer, or on the bottom)? I'm drawing a blank on a maker attribution - which is fine, I can evaluate this as an unattributed piece - but if there IS a known maker, that's good to know.
I look forward to hearing from you at your convenience,
