pressed glass cake plate (?)

OK, back to 'cleanout house' stuff instead of flowers and pets... ;-)

I suppose this is a 'cake plate', or otherwise a pretty serving dish for something during a nice dinner party or something. Measures 9-1/2" across, about 1" at its tallest. All the pattern is on its underside, smooth inside, and absolutely no markings anywhere.

Once more it is likely a rather contemporary/common piece, as well as being one more that I only rescued because it was otherwise completely undamaged...AND one more that I don't have the slightest idea what to now DO with...??? <lol>
