The defunct Mexican airline's logo features a broken-winged eagle
dropping an angry serpent.
The designer has clearly put more thought into the instructions than the
logo. They are printed right way up on the front, but upside down on the
reverse. Why? Eager as always to discover new things, I decided to try it
"1 Fold toward you, on the doted line", it says on one side.
Follow this instruction, and lo! instruction 2 appears the right way up
before your eyes: "Tear off paper and fold again."
Do that, and instruction 3 appears: "PRESS".
All they have to do now is to get a better logo and fix the typo in
