Thank you for viewing my item!    Available is an antique 1780s set of 3 volumes of Katechismus Der Natuur.   The books were authored by J.F. Martinet.    They were published by Johannes Allart of Amsterdam Sweden.    We're figuring the book is in Swedish/Dutch but we are not sure.    The books pages are all different sizes so are a little rough on the edges.    The covers are loose on the books with the back cover of one missing all together.    The plates in the book are nature related.    There are some plates that fold out and also some that were colored.    The book is original 1780s.    The books do appear to be complete but we did not go page by page so are not 100% sure.    Shipping will be Free in the US.    Outside the US will be priority mail charges on 5 pounds.
