This is from an artist that is not a listed artist, meaning not collected or well-known.
Langley was probably a regional artist that sold their work near where you originally found the piece.
It does have the 1980's pastel theme that was popular during that time. The artist used an airbrush to accomplish the
leaves/stems, then used a thick impasto paint technique to create the irises.
This painting has a current value of $60 to $75.00 retail.
