I think it is well established with most geographers trained in projections that the Peter's projection (also known as Gall-Peters Projection) is as poor a representation of land mass size as Mercator's (which was designed for navigation, not for representation of land mass size). See: Rhumb Lines and Map Wars: A Social History of the Mercator Projection by Mark Monmonier. Any National Geographic map not using Mercator's projection should be a good representation of relative land mass size. I would suggest an interrupted projection because the Winkel Tripel and Robinson projections typically distort the shapes of eastern Asia and the Americas. Interrupted also preserves shapes as well as areas.
Well, after the long soliloquy, a search of Amazon.com and Maps.com found no interrupted projections. Must have fallen out of favor. They were all over the place when I was young. I guess National Geographic's Winkel Tripel is the next best thing. Or a map that separates the hemispheres. See National Geographic World Hemispheres Wall Map
