Oh man, I totally forgot that this book, Elektroschutz in 132 Bildern, existed and that Bre Pettis was kind enough to scan in 30 of its illustrations. Take a look at some of the wacky diagrams of some of the ways one could electrocute themselves back before electrical safety. A few of them seem like brain teasers! (See the entire collection here.)
Thank goodness for proper outlets and controlled currents!
