A shame that I had to choose just one and I chose Aristotowl, submitted by Ginger!
A very clever and unusual suggestion, so thank you Ginger.
Please mail me @ email@example.com to claim the set :)
Here is a set of 4 stamps featuring Aristotowl.
They are ideal for exam results, graduation, car test passes etc.
I have left one board area blank for you to add a different sentiment of choice.
