Magnum periodically offers a curated selection of signed or estate-stamped 6 x 6" museum-quality prints for $100 through a lightning sale on their site. The latest square print sale runs June 5-9 and the theme is 'closer,' a play on the classic Robert Capa quote, 'If your pictures aren't good, you're not close enough.'

These sales are a cool way to pick up a small piece of photographic history to hang on your wall, or gift to another. There are a total of 78 images to choose from and each photograph is hand-selected by the photographer who shot it or by the agency. And with 70 years of history, there are is a wide range of beautiful, historic and emotionally-trying images to choose from. You can view them all here.
