A fascinating eight-minute look at Hatch Show Print, a 130 year-old working letterpress shop (established 1879) in Nashville, Tennessee.
More info about Hatch Show on UPPERCASE.
On the topic of letterpress, and wood blocks in particular, this office wall-hanging made me look.
Interesting to see in the comment thread on Design*Sponge that quite a few letterpress artists are showing their sadness at this use of wood blocks, saying it encourages people to break up block collections to make more of a profit.
Looks like a lovely piece of work to me.
