Hi Aileen,
Unfortunately, we do not know the maker of this mug, but our database editor Len Kling has recorded it as The Cottage Door
Here is his description:
"Coffee can, size unknown. The principal part of this wraparound design depicts a family taking its ease outside the door of their cottage. An extensive landscape opens up on the other side of this quiet scene, as a pair of horsemen travel along the banks of a large body of water, with an arched bridge, more cottages and mountains in the distance. No published reference for this pattern has been found, so it has a TCC Assigned Name pending further information."
I recognized it immediately because I had sent the images to Len. Your images are much better. With your permission, I should think Len would prefer to use yours.
Thanks for your inquiry,
Loren
