When you open the book, there is usually a section on the bottom of the 1st page that has the copyright and who it was published by. It also usually states if it is a 1st printing. You would have to look cause it could have sold out on the same year, which meant the publisher would have had to print it again. Thus making it a reprint or second printing..... Are you interested in the 5,000 creds as a GIN????
