"First Blues: Rags, Ballads & Harmonium Songs 1971-74" is a 79 page, 5.75"x8.5" hardcover written by Allen Ginsberg and published in 1975 by Full Court Press. The author signed the title page. 

It's in good condition. The dust jacket shows small brown stains at front bottom, light edge wear and soiling. The grey cloth boards show minimal wear, a tiny spot to the front. The ffep is creased. There's a correction to page 59 (a line crossed out), likely by Ginsberg - he reportedly made the correction to some other copies of the first edition. The binding is tight.
