Roaring twenties

This rather handsome advert for Douglas motorcycles appeared on the back of the May 1927 edition of The Strand Magazine. I don't think I'd heard of Douglas bikes before but fins on t'internet that they were an important British manufacturer during the First World War; were the inventors of the disc brake; and pioneered the production of dirt-track bikes. How many of their customers rode them wearing kilts is another question - actually the chap seems to be putting the Vs up to anyone who'd dare ask.
