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. 

Trouble in Triplicate (1949):

• The dustjacket as some unique features:
• The front flap has the price ($2.50) at the top and "The Viking Press New York" in a red block near the bottom. 
• The back flap is completely blank on the book club edition. 
• The title page title is in red on the book club edition instead of black. 
• The list of books is only on the first edition. 
• The copyright page has a colophon and "Printed in the USA by Colonial Press Inc" on it. 
• The bookcover is yellow cloth with red lettering.
• I have included an animated GIF file that compares many of the relevant points for a clearer understanding.
• The first edition measures .9" x 5.6" x 8.3"
• The book club edition measures .9" x 5.7" x 8.55"
• I also have a video on our YouTube channel you can watch here
