This was the Amsterdam Typefoundry’s Hercules, put to surprising use on the dust cover of a collection of poems by famous (socialist) Dutch poetess Henriette Roland Holst-van der Schalk. Originally issued in Germany as Titan(ic), later marketed under different names and invariably as foundry type, by a variety of foundries.
The publisher of this 1951 hard-cover book is the type-conscious W.L. & J.Brusse company in Rotterdam. One of the book designers most active for the company was Wim Brusse in Amsterdam – son and nephew to the two founding brothers – and he might be the author of this anonymous design.
