A plan of the ancient Greek city of Olympia, the religious site (with an important temple to Zeus) where the original Olympics took place. A high quality .jpg, 600 dpi, and at least 10" x 10" in size, which makes it suitable for printing as well as projecting (unlike many images available on the net).
