Once I'd recovered from the sheer wonder that is Hatch Show Print (on my visit last October) I managed to pull myself together enough to raid their $3 pile. The events advertised were dubious in terms of potential wall display (a Republican rally poster anyone?) but I selected on the basis of the lettering with the intention to 'do something' with them at a later date. True to this internal justification, I got out the guillotine to create a new 'Thank you for your order' stamp for Bloomfield & Rolfe orders. It wasn't an efficient way of doing things, but it was a tactile and very satisfying one.
