The fifth and final set of 20 Great Ideas books from Penguin is set for August 2010. The first three covers have leaked out into the world, so here they are. I imagine that David Pearson is the man behind the overall look, with other designers contributing.
UPDATE: The top and bottom covers are by Phil Baines, with the middle cover by David Pearson.
The Great Ideas books always look so nice that I'm willing to overlook the fact that Penguin is also publishing something called Psychic Cats in August, a completely non-ironic book of bullshit by the author of An Angel Called My Name: Inspiring True Stories from the Other Side, and other such nonsense.
