Vintage Nasco Japan Venetian Triangle Cased Glass Decorative Bowl

Lovely piece of glassware from Nasco Japan that features three design aspects; it is encased to double layered glass, it is hand blown and folded, and it has hand painted flowers on it. Yet despite it's impressive details, these were mass produced and are not as valuable as they look. Each side is about 6" long and it stand about 2.5" tall.
