In the key of F, presumably.  From A Little Tour in Ireland by Samuel Reynolds Hole, 1892.

As we noted in the special one-letter words edition of The Shakespeare Papers (revealed here), R is the dog's letter.   Romeo and Juliet aside, we find a canine T in Outing magazine, 1885.

Here's the imp of the overturned goblet, doubling as an ornate capital S, from The Oxford Thackeray.  This should also be of interest: How to Believe in Your Elf.

Here are two classic Egyptian symbols as letters (from Un Tour de Méditerranée, de Venise à Tunis, par Athènes, Constantinople et le Caire by Paul Jousset, 1893), but did you know we uncovered a way to decode Egyptian symbols in the letters of any name?  We share the discovery in the The Egyptian Secrets in Your Name. Our system includes an exclusive technique for automatically reciting an Egyptian poem as you gaze upon the letters of anyone's name (seriously), as if channeling a spirit from antiquity.  We only belatedly learned that our system was hailed as one of the top mentalism innovations of 2012 ... but you don't have to be a magician to use it, and it's actually not a trick.

This ornate capital G reminds us of Number 2's signature spherical chair in The Prisoner series.  From Loose Rein by Wanderer and illustrated by G. Bowers, 1887.
