SIDE
Cross section of the painting showing the different strata making it up. In the front it is possible to appreciate the different ground and paint layers, as well as the plywood support. The back also shows a new ground layer, a procedure traditionally used to prevent the support from warping.

BACK
Two inscriptions signed by Dix on the back provide information about the painting. The first refers to the technique used and offers advice on handling:

“Mixed technique. Last layer oil. Linseed oil.”

“It should not be varnished before Sept. 27. Dix”

The second, smaller in size and located in the upper right corner, gives detailed information about the varnish’s commercial brand: “Lukas matt. Mixed with beeswax 50/50.”
