Answer:
3 Things I noticed - Map B seems a bit Outdated, Both maps have Florida in the same place and look very similar, Map A has more Dark Gray colors than any other color.
2 Differences - Map A has more identified states or "parts" than Map B, Map A seems like the kind of Map to be used in school while Map B seems it would be used well to determine stuff for like World War 1 and 2.
1 thing i wonder - why does the middle part of Map B, look a gun???
