These are very fine early engravings from Francis Willughby's and John Rays "Ornithology" published in London in 1678. It was the first book published in the English language on the subject of birds and one of the earliest to take advantage of the new art of copper plate engraving. Each piece is 8.5" x 13". Printed on rag paper and beautifully hand colored ca 1980. In fine condition. Priced separately. Please see my blog.
