By Alejandro Rojas, Openminds.tv Last week we wrote about the announcement that photographic slides of an alleged alien taken in 1947 will be revealed on May 5, 2015 in Mexico City at an event presented by Mexican journalist Jaime Maussan. However, as part of the announcement there was a trailer for an upcoming documentary on the slides, and with some manipulation, a screenshot from the trailer may have revealed the actual alleged alien photograph. The documentary trailer is produced by Slidebox Media. Apparently, one of the photo analysts that the slides were taken to for verification thought so highly of the slides that he decided to make a documentary about them. However, the trailer may reveal much more than the researchers intended. Besides giving a lot of background information regarding slides and the deceased couple who are believed to have been the original owners of it, the trailer also shows a computer rendering of what the alien in the slides might have looked like, based off of what can be seen in them. In one of these images of the computer rendering, what appears to be the alien in one of the original slides can be seen as the computer graphics are graphed on top of it.
