Above, S. Long and T. Buchanan — Sylvan Glade
Below, the halftone by S. Long — Pan —1914
Update: A big thank you to Chris, for pointing out that this is the work of Sydney Long, an Australian artist that I should have heard of before now. Below is the actual painting and below that a print, using the same elements. Both are the gems that I predicted they were, and now I feel horribly guilty that I presumed to art direct the piece nearly 100 years after its creation.
