Acute Priori, Ctd
Marcus Leis Allion, co-designer of Acute Priori, reviewed in Hot Type (June 2010), has written to point out that the design was inspired more by the abstract/mathematical work of Swedish artist Oscar Reutersvärd (b. 1915) than by the illustrative work of M.C. Escher.
And here’s more information on Reutersvärd, the “father of impossible figures” along with examples of his paintings.
