All are in acceptable, used condition.. HUGE heavy books, some foxing (mottling) on various pages of some of them, Couple rips on an area of the eureka books spine and dust jacket.. all are National Geographic brand aside from the Eureka book. Not perfect but pretty decent for their age. Very informative and TONS of full color photos, very cool books! If these don't sell I'm cutting them up for a project and trashing the remnants.
