Growing up together in the shadow of their mother's illness, Paul and John Nash emerged as artists at the same time, exhibiting their work in a joint exhibition in 1913.  The following year they both enlisted in the Artists' Rifles, and both served on the Western Front before working together as war artists.  Both subsequently explored wood engraving and book illustration, but otherwise their art moved in different directions and, while remaining close, they each sought to distance themselves from the tag of 'the Nash brothers'.  It could be the plot of a novel, but every word of this intriguing, personal story of brotherly love, strife and competition is true.
