Here's the first of the overprintings on the bird's tail. This is a separate block, one that is cut with some striations to add a kind of 'feather' texture:
This next impression doesn't make much sense by itself - it just adds a bit of depth to the upper part of the tail; testing showed that this was too light ...
The next overprinting - with yet another block - adds some shadow and more feathery texture:
This leaves us with - I think - six or seven still to go. You can see some of the white places that are obviously not filled in yet ...
