I found this through one of my Facebook 'likes' (http://www.facebook.com/TheAdvocate). The link below takes you to the first of a series of pages on a calendar he created for his Master of Fine Arts thesis.
He gives his reasons for choosing the format on the first page and there are 15 images drawn from various periods and places. Some of the comments at the foot of the page are interesting, but I like the style and would say that the piece generates discussion of things that often get ignored - like 'if the concept of the "homosexual" comes from the late 19th century, were the men in the Sacred Band of Thebes homosexual or not?'
One of the interesting things about LGBT history, for me, is the use of language - and the ways in which that language changes and evolves over time.
