Povey Glass Plaques

I was in Old Town recently and noticed a some bronze plaques attached to the outside of a building at NW 5th & Flanders. I took a few photos in case they turned out to be Art, and set to googling once I got home. It seems this building was once home to Povey Brothers Studio, a renowned maker of stained glass windows during the late 19th and early 20th centuries. In 2010, the building's owners decided to commemorate its history and commissioned the pair of plaques you see here. The building itself is a listed historic structure, designed by local architect Emil Schacht, and installing the plaques required city planning permission. It's not really a public art project, and they aren't obligated to document it on the interwebs for all and sundry to see. Thus, so far I haven't come across anything that names the artist who created the plaques or anything that explains exactly what they're depicting. If you happen to know, or you have an interesting theory or something, feel free to leave a note down in the comments. Thx. Mgmt.
