Vintage CZECH Art Glass Hand Blown Colorful BUTTERFLY Paperweight Rainbow Frit

Approx 3.5”. Czech Republic art glass paperweight, exact age unknown. Features a pink & blue butterfly floating above a multicolor “stump” of rainbow glass. No signature or sticker. Has a number of bubbles inside glass. NOTE

• on bottom of paperweight, along the flat edge, there is what appears to be a “dent” or shallow fold in the glass (not a chip) - looks to have been made during the making process. VERY hard to photograph to show clearly, but it is circled in last picture.
• in addition, at the bottom edge of this “dent” mentioned above is a TEENY flea bite, can be seen when zoomed in to last picture.
