I promised Chaz pictures today, but I'm getting too sleepy, so just a teaser picture and a quote from Wikipedia:

"Chekhov's gun is the literary technique whereby an element is introduced early in the story, but its significance does not become clear until later on. For example, a character may find a mysterious object that eventually becomes crucial to the plot..."

Identify the mysterious objects in the picture whose significance will eventually become clear.In this photo: Mysterious map, Mysterious pack, Mysterious helmet, Mysterious sunglasses, Mysterious red gloves, Mysterious book, Mysterious guitars, Mysterious board
