Many concrete figures are hand-painted as in this next set. Snow White is about the same size as the one above and strikes almost the identical pose except for her raised hand. The dwarfs stand approximately 9" high and each is imprinted on the back of the head with "© Walt Disney Prod." Again this set appears to be old, but similar statues are still available today.
A standing Snow White is fairly common. This one measures 17". She's pictured with the same dwarf figures as above, though their colors differ.
In another example, Snow is much larger at 41" tall; the dwarfs stand between 18" and 24".

This was only a sampling of the varied concrete Snow White sets that have been produced. More are out there, probably hiding in your neighbor's backyard or garden.
