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. 

Murder in Style (Plot it Yourself) - Collins (1960):

• This is the Collins Crime Club UK first edition
• The front flap has the price at the bottom (10s 6d)
• The cover is red cloth with black lettering and a logo on the spine.
• The copyright page says "First Published in Great Britain" (first appearance in this series)
• It also has no further printings noted and has the copyright symbol (© Rex Stout, 1959) on the top line of the four lines at the bottom of the page
• The comparison slide provided shows the difference between a first edition and a later printing.
