Vintage Original Underground 1981 Poster. Advertising music with Roy Those. Full Moon Party. Friday March 20th 1981 11 P.M. till...... Admission $12.00 860 Broadway NYC. A great vintage poster from a great time in history. This poster is in good shape some of the creases where it has been folded are starting to let loose. My recommendation is to open and frame to keep from any more damage. 22 1/2 " by 16 7/8"
