We all know the standard design of the inside of the covers of Tintin books. (If you don't remember it, check the background of the Persian Tintin Blog). The desgin didn't always used to look like that. Below is the original design, from the first edition of "The Crab With the Golden Claws", dating back to 1942.
The original B&W book was only 58 pages long. Herge was about to adopt his now-famous 62-page album lengths. So he drew 4 full-page color designs to fill in. The 'Crab' is the only Tintin book with full-page frames.
