I ran across an “easter egg” in a DeLorme Atlas & Gazetteer for Arizona eight years ago today. Apparently, every DeLorme state atlas has one of these special joke symbols, except for Maine, a tradition that started in 1986. A hero from the UK named Robin has a photo collection of the ones she’s found, but needs help with the last four.
