Hand painted figurines

It was suggested that I post these here so someone may be able to give me a little background on them. Please forgive the quality of the photos, I took them a few years ago. My grandmother used to paint figurines as a hobby. I have never met or spoken to anyone that painted these white casts of not only the above but also Royal Doulton figurines. I have no idea where she purchased the casts but this was at least 50 years ago. The Snow white and seven dwarfs seem to be casts of 1940 Disney American Pottery Ceramics. Unfortunately no one in my family seems to want them or has anywhere to store them so I am at a loss to what to do with them. Anyone out there know anything about this hobby or these figurines. For scale the orange thing in the photos is a ruler.
