This is my contribution to Youoregon's abstract Thursday - circles.  Many thanks to Robert for continued hosting of this challenge which is becoming more and more interesting!!
I have just bought a book: Why fonts matter by Sarah Hyndman and that made me try an abstract with lots of 'o's all fonts beginning with B!!
Baskerville old face; Bauhaus 93; Bell MT; Bernard MT Condensed; Blackoak stud; Broadway; Book Antiqua and Bookshelf Symbol!!
But which is which?   - No I don't know either except that I labelled my layers!!!
