Theory of authentic Radio Communication

This copy of Theory of Radio Communication by John T. Filgate was published in 1929. The cover has some wear in the form of discoloring and staining. The back of the front cover has an inscription in ink. There is some staining in the central crease of a couple of the blank pages in the back of the book. There is a very small tear at the bottom of many of the pages which does not interfere with any of the text or images. The rest of the book is clean and the binding is tight. Overall, this book is in very good condition for authentic it's age.
