Thanks for posting Nomad! I remember each and everyone of those kits....I had so many of them, but now only have a supply of the last couple of years...
I laughed at the 'Do Not Disturb' sticker....I remember that from the pre-lieflat seat days. You were supposed to put that sticker at the top of your headrest before you reclined if you did not want to be woken for the pre-landing meal.
I, too, have donated many of these to shelters and homeless organizations, alongs with tons of soaps and shampoos. We have even given a bunch of the kits to senior residences who use them as secondary prizes when they play bingo
Sorry- cant be much help with the dates....its all a bit of a blur ...lol
