To create an interesting wall collage it's an idea to mix art, photography and something else. Following is an idea for this "something else" you are looking for – old wall charts. The Australian company Erstwhile has started to republish their favorite unique pieces. Their owners had rummage through vintage shops and antique stores and discovered their love for old wall charts, how difficult was to buy some and how expensive. To make a long story short, they are now selling vintage charts of maps, botanical charts and zoological prints, those lost forgotten gems, on their web page Erstwhile.
