Here are some EQMM covers, plus an Alfred Hitchcock Mystery Magazine cover featuring some well known detectives from the realm of classic mystery. Notice the differences in cover layout of the two magazines . While both are effective, they construct a different emotional tone to draw in the reader. The classic detective portraits, do not reflect the content of the magazine directly, rather they play on the atmosphere of classic quality and collectible status.
The Hitchcock cover is introducing a character that most would be unfamiliar with, so there is a need to establish identity and setting. Direct eye contact with a potential reader entices the buyer to pick up the magazine and check look at the interior. This is basic AIDA – Attention, Interest, Desire & Action.
