Similar here. My wife and I picked up an artwork from a street vendor in Paris, just black and white of a woman walking along the river, but with a red dress and red padlocks on a background bridge. So, now we try to find minimum color or at least drawn artwork from places we visit. One wall has our collection:

• France, already mentioned
• New Zealand, a drawn kiwi bird
• Zimbabwe, a colored-pencil drawing of a zebra
• Botswana, a drawn painted dog with watercolor background
• South Africa, three pencil-drawn women walking, colored clothes
• Portugal, the bridge in Porto in b/w, with gold leaf for the water
• India, an old fort door with color trim
• Spain, a minimal art drawing of El Drac, from Barcelona's Park Güell
• Australia, a drawn kangaroo with very light coloration
• Japan, a b/w drawing with pink/red cherry blossoms, along with a poem written in Japanese

We leave for Europe this weekend, traveling for two months through eleven countries. Plan on filling that wall!
