Unless Speedwell is the publisher, this could be an amusing (and rather naughty) play on words. In the language of flowers, the speedwell symbolises female fidelity - but the word has other connotations if this is a lady and her chauffeur!
Never mind any of that old speculation. What on earth is she wearing on her arms / hands? As a muff? It looks like a fairly large dead bear with dangling paws. And if he fancies her, he's an idiot. She'd kill anything for fashion.
There are several places called Speedwell in the UK, the USA and elsewhere. I'd say it's a generic postcard that's been overprinted with the name of the place in which it was sold. This practice is still common.
Bob I love that pic....Most people cringe at the thought of wearing an animal like that.....But back then it was nothing to wear a whole animals skin......and no animal was left out......I have a monkey fur cape with jet beading circa 1890-1900....squirrel,muskrat,ocelot, and even whole birds were used
