This poster promotes an exhibition of sculpture by abstract artist Abram Schlemowitz at the Howard Wise Gallery in New York City. The poster is undated but, according to his bio, Schlemowitz had two solo shows at the gallery in 1961–62, so it’s presumably from one of those years.
There is no designer credited on the poster, but Chermayeff & Geismar designed a series of posters for the gallery in the 1960s with the same typographic treatment of the smaller text, so I’d guess this is part of that series.
Some reverse engineering was required to recreate the unaltered setting for identification, but the large titling of Schlemowitz’s name is composed with sliced up strips of the Velos alphabet shown in Walter Käch’s Schriften / Lettering / Écritures book.
The smaller text details are set in Baskerville, with Howard Wise Gallery’s logo/info set in an outlined version of Grotesque No. 9.
