Here the different shades were made by painting with varnish to stop the acid. The lighter parts were covered first, then the next shade and so on.
Here you can also see the number of print in the edition. In the lower left corner you can see 28/60, this means that this is the 28th print of an edition of 60.
After 60 prints the metal plate was changed or destroyed.
