Poor Old Tired Horse was published by Ian Hamilton Finlay’s Wild Hawthorn Press and ran for 25 issues from 1961 to 1967.

The magazine took its name from a line in Robert Creeley’s poem “PLEASE”, first appearing in A FORM OF WOMEN (Jargon, 1959):

This is a poem about a horse that got tired. 
Poor. Old. Tired. Horse.

It’s been called “one of the most important visual poetry magazines internationally” and helped introduce Concrete poetry to the UK.
