I don't recall a table photo that I've shared on byc that might have shown an antique teacup. I nevertake snaps of eggs if there's another person present and when I'm breakfasting aline,  I use a contemporary teacup.
Sadly,  I have only one hand-painted.
But lots of early transfer-ware and a little post-war austerity ware.
I wouldn't be surprised if the designs on some of the newer ones were printed on somehow.
One of my favourite things to do is invite people to choose a teacup. My neighbour up the street homes in on the hand-painted cup every time!
