Whilst looking for photos of my polydactyl cat, I ran across these and decided they needed to see the wide open spaces of the interwebs.
I had to "make up" some missing ornaments, as there was only the one, and it was gone, but if you study frames, ornamentation is a language, that once learned, makes it relatively easy to fill in the missing "words". Of course, it took some time to learn the language. Just looking at frames is a start; then there are the classics; "The Grammar of Ornament", Owen Jones, and "The Encyclopedia of Ornament", A. Racinet. Both have modern reprints. Obtaining a catalog from Decorators Supply, in Chicago, is worth the price of admission, though not focused on framers needs.
