Once upon a time printing was done with wooden and metal blocks. We still have one of the original single colour printing presses that use these old things (now converted into a die cutter).
Im not sure what im going to do with it. As you might be able to tell, I do have a slight thing for Ampersands (hence my avatar). The first obvious use, is to use it as my avatar. Which i am working on. The second use is to use it to print, but i do not wish to ruin it further.
I could use it as a coaster, but its worth too much for that.
