ghost of christmas weird
Dangerous Minds curates a truly bizarre gallery of antique Christmas greetings cards, gathered from various sources, whose message and associations with cheer and the season are rather—through the filter of a given vintage—lost on modern audiences.
There’s Krampus, of course, who’s a much greater deterrent to naughtiness than a lump of coal—which I’d wager that some Victorian street urchin would be very grateful to receive, but beyond this cautionary example these salutations are just fraught with surreal imagery—duelling frogs, dead sparrows, revolting sparrows, murderous emus and polar bears. What’s truly classic is universal and enduring (kittens, perhaps) and maybe these cards illustrate the consequences of things passing out of style and humour becoming obsolete. Be sure to check out Dangerous Minds to pursue the full selection.
klaxon or blues and twos
I vaguely recall learning that emergency response vehicles—ambulances, fire-trucks, police cruisers—in the States at least bore complementary flashing lights in red and blue to shine at the most visible spectrum both during the day and at night—though I could not remember which colour was best for either condition.
In Germany (and for the UK as well), those same beacons are just blue—arrayed for each kind of dispatch a bit differently with distinctive sirens but only on the one wave-length. If the two-coloured light system had a higher visibility profile—I wondered, why it had not been adopted everywhere. It turns out that the insight into the discernability of different spectra—which figures in traffic lights as well, and the reason for Germany’s blue lights date to 1938, like much of the German infrastructure—the Autobahn and the people’s coach. It does not have anything to do with psychological colour associations or some Doppler effect, but rather anticipating the possibility of air-raids as Europe once again began to take a belligerent posture, field-engineers experimented with different colours and discovered that while red lights sent up a beacon high into the atmosphere, attracting the attention of bomber-pilots, blue light dissipated at a much lower altitude. The convention, like equipping windows on homes with Rollladen (roller shutters) to effectively black out the lights, has endured.
