This question is about possible references to Tudors in Henry Holiday's illustrations to Lewis Carroll's "The Hunting of the Snark".
I think, the back cover illustration of the book refers to a painting depicting Queen Elizabeth I at old age: http://www.flickr.com/photos/bonnetmaker/6818523809/
Then there is a less clear discovery - which may not be a discovery at all but just some phantasy in my mind. In Holiday's illustration (the back cover), there also is a pattern which either could depict letters (if mirrored: "Anmi"?) or just stripes in the waves without any special meaning: http://www.flickr.com/photos/bonnetmaker/4521661562/
