Porcelain - no mark of any kind

[jdye]

Please, assistance needed. I do not know how to approach obtaining an answer.  With a mark, I might start there.  No mark.

I am not a porcelain collector.  I claim no expertize.

Nice cup and saucer. Very thin. Dainty flowers and butterflies. There is no mark on either piece. Purchased sometime between 1934 - 2000.
