Festive Large Bright yellow sunflower brooch is either Juliana Delizza & Elster or unsigned Schreiner.  It looks like Schreiner construction but it is hard to know for sure.  The brooch has a two inch flower with a 1 inch topaz center.  It is appox 4 inches long and has green rhinestones for leaves. Slight age related wear but overall very nice vintage.  Ground advantage shipping is $6.40.  Thanks
