The Museum may have on file some photographs of his work, which was limited to gluing an area of the mosaic that had buckled up. No new pieces were added to the mosaic at this time. Pieces of the same nature as the mask, possibly found together with it or in the vicinity, were owned by Belgian dealer Emile Deletaille. He may have exhibited them. [Note: 1985 catalogue called Rediscovered Masterpieces of Mesoamerica: Mexico-Guatemala-Honduras; 1992 catalogue] [Mijel?] Rosado, who sold the mask to Randel, told him that the people who dug up the mask burned the box in which it was found. Josue Saenz, original owner of the mask, was imperious, very wealthy, very smart; his advisor Franco was a fool who failed to recognize several exceptional pieces. When Randel bought the mask, Saenz was requesting his money back from Rosado because Franco thought it was a fake. Alex [Page?] wanted to buy the mask from Randel, but Alphonse Jax sold it to Mrs. Bliss first. Olmec find from a known dig in 1926 included many small jadeite turtles created with minimal reduction of the stone as found. Randel will try to send a photograph.
