This detail page shows several photos of the book to show what a first edition looks like.  The images are original photos taken of my personal copy of the first edition book. 

The Father Hunt (1968):

• The dustjacket has some unique features:
• The front flap has the price ($4.50) at the top and the endpapers are black instead of white. 
• The back flap has three lines about Viking Press on it. 
• The title and copyright pages are NOT different between the two editions. 
• The first edition book is thicker and the book cover is red with a black spine and white lettering, completely different, as you can see below.
• I have included an animated GIF file that compares many of the relevant points for a clearer understanding.
• The first edition measures .9" x 5.7" x 8.25"
• The book club edition measures .75" x 5.7" x 8.55"
• I also have a video on our YouTube channel you can watch here
