Nice 1st edition copy of A Debate on the Theory of Relativity, published in 1927 by The Open Court Publishing Company. The book is based on a famous debate that took place on.thr campus of Indiana University in May of 1926. Two mathematicians, one astronomer and one physicist were invited to debate for or against the theory.

This is a very good copy overall, with bright, clean pages, no highlighting or writing inside, and a strong spine. The binding is nice and tight as well. The biggest issue is that there is a stain on the spine, and on one or two small places on the front and back cover. Regardless, this is a good copy for its age. It has been priced taking all of this into account.
