Called Stepback Cupboards because the top shelving piece sits "back" from the front edge of the separate lower cabinet, they are most often made of pine or oak. It is not unusual to find one where the top and bottom were not made at the same time as one complete piece, but have been put together, sometimes referred to as "married".
This one has wonderful age and patina in its deep blues and greens. If you are lucky enough to have a stepback cupboard, layering the Annie Sloan Chalk Paint colors shown above, would give you a similar finish.
In Kentucky, antique step backs are easy to find and reasonably priced. To see more of these delicious cupboards check out my posts, Another Stepback, Dark into Light, and Colorful Storage.
