Cassini Maps - A Century of Change on a Single Map Sheet

I recently bought a framed map from Cassini Maps and ended up (it's a long story) with a free copy of this map of Exeter and Exmouth. What a beauty.

You unfold it to find 4 maps on one sheet. It's incredibly straight-forward to track the changes over the decades when it's all laid in front of you.

Now all my parents will need is one of Basingstoke and we'll all be happy.
