I painted her with General Finishes Snow White milk paint (affiliate link), then transferred the images with my Doodle Magic transfer medium.
The postcards were black & white images, so I added some color to them before printing them out.
After transferring the images, I added glaze to the entire thing, but wiping most of it off the postcards.
This French Country end table with drawers got the treatment, but with black & white images.
