Exit tango: satire on the end of a dance craze, 1914
Satirical comment from Punch Magazine on the end of the tango craze. A couple dance off, while a some what more conservatively dressed 'spirit of dancing' gladly wakes up from the "nightmare" of the tango craze. The spirit of dancing(waking up): " Well, thank heavens that's over; one of the dullest nightmares I ever met." Date: 1914

LCC-LFB Breathing apparatus entry control point
At larger fires more detailed entry control procedures were put in force to control the entry, and more importantly, the exit of firefighters in breathing apparatus. These procedures were introduced after firemen wearing breathing apparatus had died because their location or time of entry was poorly recorded.
