The drawing displayed in this page was a study piece created out of gouache and oil on tan wove paper. The final painting was titled The Staircase and both were completed around 1913. There is a large number of drawings uncovered from Leger's career, with more being discovered every year. Some of the variety of mediums in which he produced these include graphite, touches of watercolour and gouache. Most of Leger's paintings were particularly complex arrangements of geometric shapes and elements of planning were necessary to get this right in the final piece. It would be particularly hard to amend this type of content because of how every object would have been related to each other.
When you consider related artists, it is perhaps true to say that Leger went into greater detail with his study drawings. If you check out these Malevich drawings, for example, you will see how that artist preferred to simply draw out a rough form of composition and avoid adding too much detail. These would not be presentable as artworks in their own right, really, and fit very much into the category of supporting study work. Other artists went to extraordinary lengths in this medium, completing pieces which can be enjoyed and respected independantly of any other paintings. If you look at the item pictured in this page, you will find that Leger did not worry too much about the fills within his objects but more so wanted to get the arrangements correctly laid out.
Many of the Leger drawings can be found in collections within the United States, and are generally priced more competitively than his more expansive paintings. This allows institutions to pick up groups of them relatively cheapily, whilst at other times they maybe bequethed from local collectors. The Harvard Art Museums, the Thaw Collection, and the Metropolitan Museum hold many of his drawings, plus simple watercolours. A quick browse through them also helps us to understand his processes of work. There are also some portraits which may use of very minimal lines, just the fewest touches of the pen as possible in order to plan out the outline of a particular figure. He captured figures standing or reclining, often focusing on individual figures that were perhaps central to a particular piece.
Leger is known to have focused entirely on sketching whilst serving in the Army during WWI. There was simply no other resources available at this time and he is known to have missed painting very much. This spell lasted three years but he was at least able to carry sketchbooks around with him and release some of his creative urges. He is known to have produced portraits of his fellow servicemen which he enjoyd but this break from oil painting filled him with a renewed passion once he returned.
