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. 

Nero Wolfe Primer (1952):

• The front flap has no price on it. 
• This is a cute collection of three novels, And Be a Villain (A), Black Orchids (B), and Champagne for One (C).
• It was published by Mystery Guild, a book club, in 1952.
