Thienemann

F.A.L. Thienemann und G.B. Günther: Reise im Norden Europa's vorzüglich in Island in den Jahren 1820-21
2 text volumes and a volume with plates.  1824-27
The book is a documentary of the then little known mammals and especially the various seals from Iceland. The plates show the animals 'drawn from nature' in an attempt to reproduce correctly. The result is rather naive, but quite charming.
