Why are they still doing that? It's silly. Cut it out!
Also, pretty much ANYTHING copyrighted last century with a roman numeral is wrong. It's not MCM for 1900, it's MDCCCC. So there :pHmmm, I could have sworn that was how we wrote 1900 in high school, but the innerwebz says 'no', and the innerwebz could never be wrong so I'll retract that last bit…
Ah, can't find anything WRITTEN, because everyone has copied everyone else, but an image search tells another story
