This coaster features an illustration of the constellation Canis Major as a greyhound: one of thirty-two cards that came in a box titled Urania’s Mirror. For each star you see in the constellation there is a pinhole; when you lift the card to the light, you see the pattern of the constellation, which you can then identify in the sky! Brilliant.
