Jan-Simon the first stamps you posted are likely fantasies. The catalog I mentioned earlier, "Poland 1918 Locals" by J. Barefoot, indicates that there were no Polish eagles with and encircled overprinted on any of the Germania issues. The Polish eagles were applied to those stamps, but none were ever circled.
I know, got similar replies from other sources. Thank you for verifying it in the literature though!
