Denby Duchess china, 70s vintage Portugal pottery bread & butter plates set of six

Set of six bread and butter plates in Duchess pattern Denby china, 70s vintage, made in Portugal. This has a lovely spring - summer floral design, johnny jump ups (tiny pansies or wild violets) on pure white.

These are 6 1/4" in diameter, all in excellent condition without chips, wear or staining - I don't believe these were ever used.
