My Rowland & Marsellus plate is not among any of the ones on your site. How can I find out about it? My great grandparents lived in England and probably gave it to my grandmother who had it as long as I can remember. Then again, she loved music and might have purchased it while in England. She was 103 when she died in 1998 and it was passed down to my mother and then to me. It is blue & white from Staffordshire England and the subject is Famous Musicians and Composers. The faces are around the rim of the plate. See attachment for the markings on the back.

No better or worse than the others !! This company did not make anything themselves !! They were importers and purchased from many potteries in the UK !! The only thing they did was to put their stamp on it !! Their items were for souvenirs !! No way to know when it was made because you do not know who made it !! There were many Staffordshire potteries !!
