According to Manverse.com,
This is the picture of a real Extraterrestrial’s mummy.
While the group was viewing exhibits, they were invited to view a special room in the back, which is where the alien mummy was being housed. This photo was taken at this time by one of the team members.Museum records state that the mummy came from a group of locals who were scavenging what they thought were Inca tombs hidden in a nearly inaccessible cave high in the mountains near Tres Cruces. The cave was decorated with strange symbols of flying snakes exploding in the air and falling into a river. Unfortunately when the team returned to the museum in 1996, they discovered that the museum had been burnt to the ground after thieves stole all of its’ artifacts.
The mummy’s current location remains a mystery.”
