Hi Wayne,

Thank you for contacting Mearto with your appraisal inquiry.
The Tiffany Studios designed the original 'dragonfly' shades, which proved so successful that they were replicated extensively by numerous companies, in varying degrees of quality. Your shades are among those that were replicas of the original. It's unusual to have a set of three but the quality is of fair to middling skill and they are small - not very old (second half of the 20th Century) and worth $50-75 each.
Based on the photos and information provided, and subject to examination, this is:

A set of three Tiffany style 'Dragonfly' style stained glass light shades
late 20th Century
Each in tones of green, red and orange
(DIMENSIONS)
CONDITION: all three appear to be in good condition, commensurate with age
$50-75 each or $150-250 for the set of three*
*represents a fair-market value for auction purposes; retail or asking price may vary.

Please let us know if you have additional items to appraise, and thank you again for using Mearto.
