Some are fancy and special, but even the more utilitarian ones have a special charm. Here are a few I have in my shop right now...
The first one is a Royal Albert, and the second one is labeled Old Royal, but they go very well together.
This one is Royal Albert Heather "Heather Bell" in blue bell (most of the ones I have seen are pink, not blue).
This pretty blue floral cup is by Vanderwood, England. I love the Art Deco shape.
This one is just marked with a Japanese symbol so I don't know the make. But it reminds me of my grandmother.
This elegant teacup is by Adderley, England. I love the handle. And at the bottom of the cup there is a bright floral bouquet.
