Modern Art Screen Print - Unknown Title, Unknown Artist; 23"X16" - 12 of 22

I apologize for the lack of information here, but I simply cannot recall the circumstances under which this was purchased beyond a few scant details. I bought it a long time ago at a gallery while in Boston visiting my alma mater. I hid it away and managed to forget about it until just recently when doing some spring cleaning. I cannot remember which gallery, or the name of the artwork and artist, and other crucial details. The piece has been numbered (12 of 22) and signed (the signature is illegible). If anybody has any information on this piece, I'd be very grateful for it! Measures 23"X16" 10+ years old
