1930's-1940's Original Pair signed "Gill" Art Deco Airbrush Hawaiian Style Paintings

Pair of original 1930-1940's(?) Art Deco Airbrush Hawaiian paintings each signed "Gill" (I beleive in pen) and framed by "Parmelee San Francisco". I recently purchased these at a Hospice Thrift Store where they were donated. They are so beautiful.  These airbrushed paintings are on highly textured artist's paper (between the glass reflection and my lack of photography skills I could not capture the textured paper in a pic) .  The backs have "Created by Parmelee San Francisco" foil labels on the paper backing and by those is hand written in pencil 18" x 22" Gill #7 & #8 respectively. They measure with the frame approximately 32" tall x 28-1/4" wide. The colors are very deep, rich and vibrant. I do not see any damage to the paintings themselves. The  (profile painting) has a significant crack in the glass as seen in pic #6  (I do not see where the cracked glass has affected the painting itself). The painted wood frame has some paint loss/chips & minimal separation at the jointed corners. What looks like "matting" in the frame is also painted wood with grooves (the glass lays under the wood "matting"). They both have their full original paper backings with minimal wear and wire hangers.
