In Cryptograms, every letter represents some other letter, and it's consistent throughout the puzzle. I.e., if you determine that the letter "A" represents the letter "X" at some point, it will represent the letter X throughout the entire puzzle. In this case, I compiled a list of things that all have something in common. The two word phrase at the top is the description of the list and each line has its own item for the list.
What is this a list of?
