T. S. Eliot’s 1931 birthday party invitation to his 4-year-old Godson Thomas Faber has been posted at Letters of Note. Such letters to Eliot’s Godchildren were later collected in Old Possum’s Book of Practical Cats, and the verse from this letter reads in part:
Pollicle Dogs & Cats, draw near;
Jellicle Cats & Dogs, Appear;
Come with your Ears & your Whiskers & Tails
Over the Mountains & Valleys of Wales.
