The painting shows a crowded table inside the restaurant of the Hôtel de la Tour Eiffel at 1 Percy Street, London.

The six seated men are, from left to right: Cuthbert Hamilton, Ezra Pound, William Roberts, Wyndham Lewis, Frederick Etchells and Edward Wadsworth.

[1] The Tour Eiffel restaurant had been visited frequently by the Poets' Club of T. E. Hulme, including F. S. Flint and Ezra Pound, and thus had been a centre for Imagism.

[2] As Richard Cork has noted, however, Robert's picture is "an imaginative evocation rather than an historically accurate record" of the launching of Blast, which actually took place with a meal at the Dieudonné Restaurant in St James's in July 1914.

In addition to the artists present in Roberts' painting, the exhibition featured Henri Gaudier-Brzeska, Bernard Adeney, Lawrence Atkinson, David Bomberg, Duncan Grant, Jacob Kramer and C. R. W.
