Four Men and a Shed

 Four happy chaps, posing outside an old-fashioned shed.  Probably from the early 1960s, and possibly from Jersey.

So, why are they so happy?   They've just completed a shift of Coca Leaf Harvesting, and thanks to the "help-yourself" policy, they're as high as four kites.

Bonus 2- How does horseshoe crab blood protect the public health?
