I’d like to point you to a history of Study Group, but lacking one I’ll rattle off what I know of it from memory (citations needed).
In the early 2000s, Study Group 12 was an annual comics anthology with an artist’s book sensibility that was edited, published, and printed by Zack Soto. If I was to wager, I’d guess Zack was inspired by Jordan Crane’s Non, another high-design anthology series of the era. If memory serves, Study Group 12 was also a somewhat-secret online message board, and eventually a webcomic publisher (which it still is). As far as I can tell, sometime after 2010 the “12” was lost, and Zack Soto’s publishing platform was known thereafter as Study Group. It’s now a robust micro-press that, in addition to publishing its anthology (now called Study Group Magazine), puts out single titles by authors like Sam Alden Farel Dalrymple (no small boast, those are two of the hotter names in indie comics right now).
(Like I said, I’m just rattling this off from memory. I’d welcome Zack or anyone to correct any errors here.)
Today would be a good day to head over to Study Group and order some swag.
