Letter frequencies, like word frequencies, tend to vary, both by writer and
The Ultimate Alphabet less prominent than others; the hardest to spot is in the "W" painting, where he appears (representing, of course "Wilks") in a tiny cameo on a reproduction of the cover of his earlier book "Weather Works".
