Focus on this artwork and explain the Technique.
In addition to the format and the programmatic title, the technique is also unusual: oil on a plaster-primed canvas stretched onto a stretcher, which Klee only used in few cases until 1929 and not very often later. Highway and Byways' is therefore unreservedly a key work of Klee.
For the composition of the painting, most of the line structure was scratched into a fresh plaster base, in the case of the two boundaries of the main path with a sharp stylus and with the help of a ruler, in almost all other cases with the free hand and a coarser instrument, which has left warps and ridges in the primer in some places.
