So here it is; The Mad Hatter's very first brain teaser - and it is of course intended to be just that.
This photographic puzzle has two elements to it.
The first is the more straightforward, namely:
What is the common link between the gallery of 17 images set out below?
The second element will be a little more challenging, as it will require you to explain exactly how each image fits into the overall theme of the puzzle.
So, are you up for it? What have you got to lose?
That's right, absolutely nothing at all.
Now, if you would like a further clue (bearing in mind that you have been given a minor one already in the introduction to this item), rest assured there will be another one of those in the Library's next update.
But if you think you might already have a solution, even if only to Part 1, we would love to hear from you. Just go to the Comment section of the Returns page, and send us your thoughts so we can let you know by return email if you're on the right track.
