Vintage Art Glass Vase with Metal flower Frog Czech?

This neat little vase has a metal frog on the top(which is removable, for easy cleaning) and nice swirls of red, orange and yellow colors. This piece may also be referred to as a potpourri. It resembles Czechoslovakian glassware of the period, but is unmarked. It is in excellent condition and would be lovely in a sun or bathroom window. ~Enjoy!
