I'm getting three. One on my right shoulder, one on the left, and one near the shouldnt blade of my back.
On my right shoulder: http://images4.cpcache.com/product/tower-stephen-sigul/257532614v22_225x225_Front.jpg
With the Roman numerals for the number 19 because I took a lot of life lessons from that book.
On me left shoulder:
A rapier pointing done with a golden hilt and steel blade. The to the left it will have an "S" that connects to the blade. to the Right it will have an "A" with the top starting near where the bottom curve of the "S" connects and the bottome base of the "A" connects to the rapier

^ Would most likely be the model I use, since its rather close to the sword I fence with. I would get it for mostly personal reasons really.
Finally, on my back (maybe between the shoulder blades), I would get a Round shield that had the twelve birthstones going around it like the face of a clock with a Golden GO in the middle, the O surrounding the part of the G that makes the T and J shape near the bottom and right. I would also have a fox sitting on the left betwen the birthstones and the G and and Owl on the right between the O and the birthstones. I would then have a Broadsword behind it with a golden hilt, steel blade, an dark emerald on the pommel and an emerald green grip colouring the same colour as the emerald on the pommel
Something close to this for the sword (Edit) since its close to my broadsword:
