My guess is that this is an example of craft/shop-ware produced in some quantity , perhaps for tourists in European climes .
It seems probable that the section of the paper backing (which would be a bit unusual for an antique tile , since they are usually made from fired clay) that been ripped away once had a 'made in' (or price) sticker on it .
There seem to be protuberances under the paper backing (looks like brad-heads , or something like them) of a type which also would not be seen in antique tiles (@ least in my experience) .... perhaps the mat'l the hand-painting was put on was/is not tile (@ least not the 'fired' type) .
You might be able to detect what the mystery 'brad-like' bumps on the backing might be by gently slicing through the paper to expose one (wouldn't worry a great deal about damaging it's value by doing so .
Worse case , you might find a plastic grid , coated in plaster ..... hope not , but just sayin' ...
Cool little item , wolfhouse .
A loose translation of a 'transfer' would be very like a printed decal , which is applied on the top of a surface .
