i hesitate to compare us to johnny brewton for fear of sounding horribly arrogant and self-aggrandizing, but it kind of reminds me of bagazine, only with much simpler contents. it definitely is a nice little extra, though, if i do say so myself. i don't know of anyone who has done this with an anthology, though. part of it is that you have to have contributors who are cool enough to bother to send you the envelope full of signatures, rather than a bunch of self-important poets who think they're too good for that shit or start hitting you up for money or more contributor's copies in exchange for their trouble. thank god we didn't have to deal with any of that.
also, and you can't really tell this in the pictures, but the text on the envelopes is SO COOL and a huge bonus/companion piece to all the poems. can't say who it's by or what it is - so please don't guess and ruin it! - but i'm super excited about it. plus, the printing went really well, and we were able to get the ink/printing to look just like an old, worn-out typewriter, which is exactly what we were going for.
