These stickers are a part of a guerrilla art campaign i've been working on for quite a few years called God Pave The Queen featuring the mugs of my favorite British royals from history.
At one point, I also wheat pasted at 4ft tall version of Queen Victoria in the San Francisco Mission. Perhaps you've seen these little ladies about on your local lamp post, or mail box. She's everywhere!
Shhh don't tell.
