Or was it this card?

I walked past the bank again yesterday. Queen of Spades this time. Any takers?

Is this the card you were thinking of...?

Five of diamonds? Anyone thinking of the five of diamonds? No? Oh well, I guess in time, if enough people read this post then at least one of you will have been thinking of the five of diamonds.

The reason I ask is that every so often I walk past a certain high street bank down the end of our road, and in the window of the bank is a playing card. Not every day, just some days. The other day it was the five of diamonds. So I took a picture.

I don't know why the card is there, I can only assume that somebody who works there (or a customer?) is putting the card there as some kind of set-up for a magic trick? Any other suggestions?
