Monogramoflage   +  Vintage

Vintage walls?
My room is quite a large space, and there is one wall which is just a huge sparse space with nothing on it.
I have been trying to find prints which I think would suite my French provincial room.
I thought vintage prints could be an idea, here are some I'm thinking of... I think three large prints would suffice in the space. There needs to be a theme of sorts.I am still undecided if prints such as these may be a little much in a space which is predominately white/cream. Maybe I should opt for re-prints of Monet etc with softer more pastel colours and blending in their art works, instead of bold harsh lines.
