There is a little info here !! Not much is known about these souvenir plates and none of the artists names were ever recorded !! Made between 1892 and 1907 !! I would guess your artist had a tabby cat named Jack !!
Not sure about the value the expert places on these plates !! I would check ebay for current sale records as well as other sites !!
