A critical study of the early separate publications of Charles Bukowski (1946-66) with particular attention to three offprints issued in Targets (1960/1) and The Outsider (1961). Includes a revised checklist of Bukowski's 27 earliest publications. Cover title: Signatures. View text at http://www.archive.org/details/ASignatureOfCharlesBukowskiPoetry. NOTE: this study was accompanied by the first separate edition of Bukowski's third Targets Signature, A Signature of Poetry (issued 29 September 1987 in an edition of 66 numbered handbound copies, as twobitter 27); the poems having originally appeared in the last half of the final issue of Targets (15) in 1963, rendering a contemporary offprint or separate issue of the section impossible.
