One of a kind art banner of an event on wall street  the featured many artists including the works of David Ellis.  This information came from a member close to the family that had this banner and many Robert Ellis art works. 

Banner measures 7' x 7'.  Black and yellow stitched nylon material for outdoors. "LIVE ART ON WALL STREET" Jan Feb Mar

I can jot find this particular event to confirm.  But someone was there.... and might want this banner.
