Rodolfo Padilla is known for this specific style of mug. It's an unusual design with a round shape but one side is flat. On all 3 rounded sides there is a different piece of fruit artwork.
The handle is also unique in that it is rectangular and quite large.
Features Rodolfo Padilla's signature on the bottom of the mug.
Condition note: there is a small depression on the lower left part of the handle. This is not damage but rather is due to manufacturing. Please see the red arrow pointing to this in the 3rd photo.
