I think that the picture was
taken in the 50' because is in black and white and I don't see signals of any
other decade, the person there is a magician in the middle of his act and he wear a black suit. I think
he has a little box with too many birds for the next trick where he will
disappear and the white's birds will fly for all the stage, later the band in
the back appear and play a celebration's song, but after a few minutes the
magician is not here, and start the general worry.

The band in the back start to play again, they know it
before, the people start to clap when they stand up. He do a bow and all the
stage exploded killing everyone included him.
