As is apparent from its caption, De Driehoek wants to purely orientate itself towards Constructivism. With this, it is the first and only publication for Belgium with that goal. Just as with Het Overzicht, De Driehoek is then also a personally financed undertaking. With the new Co-Director Duco Perkens, the pseudonym of Edgar Du Perron, Peeters finds the necessary financial means for this new initiative. Originally Paul Van Ostaijen (1896 - 1928) is also an initiator, but just as previously with Sienjaal, it does not work out for the literary frontman to sign off on it and gradually he breaks away. Yet, he still delivers important contributions, amongst which the poem that has become a classic in Flanders, Marc groet ’s morgens de dingen. It is then also in the literature that De Driehoek excels, especially with the bi-monthly Cahiers van De Driehoek, in which Du Perron publishes, along with Van Ostaijen, Gaston Burssens (1896 - 1965) and Roel Houwink. Via this publisher’s mantel that has the intention of promoting its own colleagues, De Driehoek also publishes five series of postcards by Peeters, Jos Léonard (1892 - 1957), Victor Servranckx, Karel Maes and Maurice Gaspard.
