Thank heavens this image does not show a super-rare glass insulator smashed to bits next to the book :-O

Added note: I think a Dr. Cubic Rubin (who contributed to this manual) suggested that collecting stuff was the best therapy a human being could experience ;-) He did not specifically mention insulators.... However if the thought came to mind methinks he certainly would have recommended insulator collecting as among the most personally beneficial, drug-free stress therapies on the planet....

Very especially on account of the great friendships/relationships that have been and are to be found within our hobby ;-)
