Antique Copper Lusterware cup Staffordshire England small tumbler copper luster

Description

This listing is for a lovely Copper Lustreware cup in very nice used condition for an antique of this age. I am not an expert, but my research leads me to believe that this little tumbler was probably made in Staffordshire England in the mid 1800's? (Notice the question mark...I can't be certain...) This is a tumbler style cup based on its shape (no handle) but it is very small standing at only 3 inches tall.
The condition of this cup is very nice! The exterior is in very good shape with no large flaws .The blue band still looks lovely. I do see a place on the bottom rim that looks like a flaw that existed before glazing. Please see photos for details. The interior has some gentle crazing and flea bites and a little discoloration from age. Even at that, it is still a lovely piece!
Please feel free to message with questions!  I am always happy to answer!
Thanks for looking!
