Prior to the watercolors, Hasbro issued a "Simple As ABC" series of oil paint-by-number kits. They date from the 1960s. Here's a look at a few completed panels.
Apparently, these next four panels were part of the oil-based sets too but were done with watercolors instead.
There was also a paint-by-number Oil Painting with Sculptured Frame series. The Snow White kit dates from circa 1967. Included eight oil paints, one 16x12 panel. and one frame.
