ahhh, sorry i misread your previous post... i thought you said the whole thing was cut from rubber... i'm a sucker for wood type.... started collecting it a few years back, and i have a 1.5' wood 's' above my toilet. i'd love to see the press they used for that!
Brian, this is wood type (the bottom type is lead) that's probably at least 70 years old. I buy it whenever I can find it for a good price. I also borrow some occasionally from an old printer friend of mine. In some of my posters I use handcut type also.
Sometimes. Sometimes I make a more temporary, cheaper, easier to destroy plate as in the case of this one. The images are thin foam rubber mounted type high on particle board. Basically a big rubber stamp. The kind of thing that makes FINE letterpress printers cringe and call me "the evil one". Here's one that was linoleum http://www.gigposters.com/posters.php?poster=15003
