The stamps on the bottom are a bit mystifying. One says Made in England and the other two say Staffordshire England. The one with Made in England might be from a different batch because the transfer is much sharper than on the other two. I know they are Winkles because they match this plate from a gravy dish set. It's called "Autumn".
And I bought them because they fit my (loose) rule: new shape or new pattern.
