What a bag! First, there's a
join-up-the-dots puzzle, with the explanation "Santorini, Akroteri,
Room D2. Detail from the Lilles Fresco, 1.500
BC". (If you actually try to join up the dots, you get something that
looks like vomit splatter.)
At the bottom, there's the instruction "In the event of sickness
please call cabin crew for assistance". Don't forget to ask them to
help complete the puzzle before you use the bag.
Oh, and then there's the news "This bag may contain bio-hazardous
waste after use". Presumably, "use" here means "used
for throwing up" and not "used as a puzzle to distract small
children from the meal we will serve you".
