Theme Thursday: Square

I'm a bit late again this week for Theme Thursday as I've been working away this week. I like the 'square' theme and have found something that fits the theme in 2 ways.

Vintage postcard of Leicester Square, London, c.1905

and on the back of the postcard ... a 1905 Alfreton squared Circle postmark

100's more vintage postcards can be found on my web site
