It is interesting how much bookbinding has changed in the 50 odd years from 1900 to 1950. The skirts and hairstyles are much shorter. The stool you sit on also looks to be metal, rather than wood. Thanks to the sharp eyes of the John Townsend (aka. Anonymous Bookbinder) for bringing this to my attention and supplying these images. John has noticed that 23 illustrations originally done by Noel Rooke (Cockerell’s illustrator) are highly likely to be redrawn by Mrs. Edna Kaula (Diehl’s illustrator).

Oh I’m sorry, I didn’t see this sooner! I commented on this in the paper I gave at PCS almost a decade ago. I look forward to talking to Mr. Anonymous Bookbinder about it – I’ve found some correspondence Diehl had with the publisher and illustrator. Just stumbled upon this post today as I looked back to your hammer post for the wiki, which is about to go live for Women’s History Month. Are your ears burning?
