In 1967, The Times reported that tourists again saw a circular symbol with an "R" in it, 200 feet in diameter, sketched in the snow above the St Anton ski resort. The symbol was also reportedly seen many times since its first appearance on the Great Pyramid of Giza: on the Lincoln Memorial, on a cliff in Dover, even on one of the stones of Stonehenge. On all these occasions, it was actually Jean-Pierre Rex's work, using his powers acquired from his use of Om-Tsor. (PROSE: Revolution Man)
