These Masonic tracing boards by Lady Frieda Harris were removed from the archive where they appeared so I am reproducing them here.
With this original note by Tero Hynynen:
Lady Frieda Harris is best known for her designs on the Thoth deck, but here’s something different: three Masonic tracing boards. Having been a mason herself it’s not a big surprise that her artistic and creative nature would’ve lead her to design and paint a set of important symbols from this another school of thought. The use of synthetic projective geometry is once again apparent in these paintings. I wish there’d be more art work by Harris available. (Original link)
