About ten shillings and tenpence!

Alice could have bought the mad hatter's 10/6 top hat, and still have had change, for the price of one second-class postage stamp today! Sharing this thought with you as I prepare to write crimbo cards. Talking of spending money, having slept on the dilemma, I've decided I will chip in to the Blipfuture initiative. It might not work. It might, at best, simply achieve a stay of execution for Blipland,  but it's worth a try. If the minimum cost isn't achievable, I lose nothing financially; if it proves viable, everyone gains. Let's wait and see and hope for the best.

One question: Can anyone make out what the red blob on this stamp's picture is meant to be?
A giant hedgehog, maybe?
