So, Thursday I got a call from Michael's that my picture framing had been completed. Friday evening, I was home in time from San Luis Obispo to go pick them up.
Here is the "Discworld Massif " by Paul Kidby. We covered up the original name, but added the plaque.
Here is the "Speechless" reframe. You can see the two bits of matting (the black and gray) from the original framing.
Here is how we hung them on the wall in the stairwell.
