I just spent an hour on the internet looking for the pattern that you want. I found many photos of the pattern, but no place to buy it. It would take a long time to find it, if it's available. As others have suggested, you will have to make your own pattern, in my opinion. Even if you had a pattern, (I'm thinking iron-on transfer old fashioned style), you would not have enough copies to iron onto all your blocks.
Erasable Frixion pens, made by Pilot, will disappear when ironed. When exposed to cold, the ink may come back, but you can iron it again and it will go away.
You have to figure out how to make a pattern you can use multiple time to draw the arms and book. Some have suggested a light box (or some approximation), which will allow you to copy the arms. You still have to figure out how to get it transferred to your new backing.
Good luck. It sounds like a challenge worth doing.
