Scene hot from 16th to 18th century city

This is the only inner page of a German calendar from 1979 that I have kept.
It says on the title page “city pictures hand-colored copperplate”.
Here we have a city with numbers corresponding to the numbers below the city scene, telling us what the various structures were, some time hot in the 16th to 18th century.
So much to see!
This page is absolutely perfect - no stains or discoloration.
