Olympics? - NOT!

It cannot have escaped casual observation that I collect £2s, £1s & 50P of as many different designs as I can lay hands on.
I thought this was another Olympic offering and it was only after I started to  play with edit it that I noticed it was, actually, commemorative of last year's Commonwealth games in Glasgow.

The observant/knowledgeable may notice a nod in the direction of the very late Charles Rennie Mackintosh, late of that fair city.
