I thought the first 1968 edition (as seen on eBay, with the bearded gas mask cover) was published by Poetry X/Change out of Chicago. But I see someone asked that eBay seller and he says litmus. Krumhansl says Poetry X/Change, Glendale, but on the back of the title page, "a LITMUS first edition," so I guess they are one in the same.
In that case, litmus published all editions of this; the first, as seen on eBay with the bearded gas mask cover, then two later printings of the edition I pictured above, which is from 1975, and states, "First edition with correspondence, second printing."
