Gavin Delahunty of Dallas Museum of Art discovered a lost Jackson Pollock “black painting” (example above) while putting together a show Wade Guyton and Julie Mehretu inspired him to curate

Mr. Delahunty has secured 31 black paintings between the two museums. (The largest previous museum grouping was 17 in William Lieberman’s 1967 Pollock retrospective at MoMA.) “Number 24, 1951,” classified as missing in the 1978 Pollock catalogue raisonné, was found in a private American collection and will be one of several works on view for the first time since the early 1950s. Mr. Delahunty will also show five of Pollock’s six existing sculptures, including a terra-cotta piece painted black that resembles a Medusa’s head and looks like a three-dimensional black painting.
