We were challenged by the American Antiquarian Society to post seven days of #bookcovers without explanation or review.

Day 7:

Proctor, R. A. The Expanse of Heaven: A Series of Essays on the Wonders of the Firmament. New York : D. Appleton and Company. 1889.       

We had so much fun participating in this challenge! Thanks for joining us!
