Man, mustache, navel 

Jean Arp made this lithograph titled 'Man, Mustache, Navel' using the technique of abstraction. Arp was involved with the Dada movement, which arose out of the horrors of World War One and critiqued the institutions that led to it. Arp here is challenging the traditional role of art as something representational. We can see this artwork as part of the broader social and cultural shifts that were happening in Europe at the time, where artists and intellectuals were questioning established norms and values. To understand this piece better, one could research the Dada movement, the cultural and political context of post-World War One Europe, and the artist's biography. We need to consider this lithograph not just as a formal exercise, but as a product of its time.
