Map samplers have a long history, and antique ones are often highly sought after. There are some twentieth century examples around. I'd place this one early to mid-twentieth century in date. In coming blog entries I will show you several others: at least three of which share stylistic similarities with this one, in the figures and the font. Being fairly small, it just has room for a representative national figure for each of the countries of the UK, a Scotsman in his kilt, an Englishman in his hunting kit, a Welshwoman and an Irish woman in their national dress (curious, isn't it, this gender split? Easiest gender with which to distinctively represent each country - what's an Englishwoman's national costume? An Irish man's?). Top left, the coat of arms; top right, a compass; bottom left, a scale in miles.
If you can shed any light on the origin of this design, where it was published/printed/sold, please do leave a comment with any useful links.
