Antique Silver Mickey Mouse Teacup

I found this vintage teacup in a box of goods I bought at a garage sale. It seems to have an early style Mickey Mouse on the front. It is approximately 7cm tall and has a diameter of 6cm.

The bottom of the cup has a silver rating of 835 and a three pointes crown hallmark containing the letters "HB".

I will provide the photos I think are nesesarry. However, feel free to ask for more.

There are no other identifying marks that I can find.
