Henry Holiday's working drawing for "The Landing" from "The Hunting of the Snark" by Lewis Carroll (1876) was presumably intended for his eyes only...

...but the Bellman's penis is finely detailed.

"Just the place for a Snark!" the Bellman cried,
   As he landed his crew with care;
Supporting each man on the top of the tide
   By a finger entwined in his hair.

Picasso submitted this pencil drawing of a heavy-thighed man to enter the Barcelona School of Fine Arts in 1895 when he was14.

A jovial minotaur and man in Picasso's 1933 "Bacchanale" share a post-coital drink.

The penis is drawn very simply.

Keith thought that the omens at his birth were auspicious: "Apart from being a healthy baby it was observed that my penis possessed a loose and easily retractable foreskin which was not considered necessary to circumcise according to the custom of my class. For this piece of good fortune I have had many occasions to be grateful."

M. C. Escher's intiguing etchings routinely show any nude males as intact, such as this Buddha-like figure (in Mosaic II, 1957) ...

... and not only the optimists emerging from this frieze (Encounter, 1944)

but also, as Escher's working drawings show, ...

... the pessimists.

David Hockney's 1967 illustration to C P Cavafy's poems stresses line, rather than shading, giving a flat look to the model's penis, though the sulcus and acroposthion are indicated.

Conversely Francisco Lòpez's 1973 nude torso is finely shaded, emphasising the penis' dorsal vein.

"Actor (Richard)", painted in 1979
by R. B. Kitaj, has a "peeper",
a shorter than average foreskin.

While the character of Gollum in the film of The Lord of the Rings is almost entirely computer-generated and wears a tiny loincloth that doesn't seem to hide much, oversized models were used by Weta Workshops to help make him so lifelike, and a picture of one in Cinefex magazine shows the artists conceived him as intact, as is a maquette of the Cave Troll in the Lord of the Rings exhibition - as of course they should be (but it wouldn't be so certain if they were made in the US).

Picture to come.

has a clearly delineated peeper.
