I bought this a while ago, couldn't resist it. It's an original WW1 gouache artwork design (for a Post Card), signed by the artist J.H.R. (John H. Roberts), and with artists stamp on the reverse (J. H. Roberts, The Studio, 12 Grand Avenue, Hove, Sussex). In addition to the 'Red, White and Blue' ....I think that the iconic imagery of the British Lion, standing on ‘the green grass of home’ upon the White Cliffs of Dover, facing the enemy, under a flying Union Jack, really captures the sentiment of First World War British home front sentiment; a strong sense of patriotism, keeping morale up and our island nation sense of history and invincibility. Or, maybe I am being over sentimental! Anyway, thought I would share it...
BTW, gouache is a type of water-soluble paint that, unlike watercolour, is opaque so the white of the paper surface does not show through.
