a face is symmetrical like a Rorschach blot
In the graphic novel, Watchmen, written by Alan Moore, there is a character named Rorschach who wears a mask with a Rorscach blot on the front. Moore is a self-professed Pynchon fan: he referenced V. in V for Vendetta and has mentioned Gravity's Rainbow in interview. It is possible, not to say probable, that Moore was inspired by this line.

Bornando el Manto Terrestre
Remedios Varo (1908 - 1963) was a surrealist painter. Wikipedia entry

Bill Brown notes that "Pynchon saw Bordando el Manto Terrestre when, as part of the first full retrospective of the painter's work, it was displayed at the Palacio de Bellas Artes in Mexico City in 1964, a year after her death at the age of 55. Painted in 1961, el Manto (oil on masonite, roughly 40 by 48 inches) is the central panel in an autobiographical triptych. It is possible that Pynchon, writing Lot 49 in 1965, recalled the painting from memory or incomplete notes, and not with a reproduction of it set in front of him. He gets a lot wrong."
