Frogs, butterflies, flowers and a haunting landscape are among the images local artist/illustrator Melanie Therrien will display throughout April in the Art & Ale Window at Gritty McDuff’s in downtown Auburn. Therrien is a resident artist at Captive Elements Art House in Lewiston and this year opened Wicked Illustrations Studio and Gallery, also in Lewiston. This piece is titled “Blue Frog II.”
