For the unenlightened, the famous hand on the cover of the 1981 KISS album Music From the Elder does indeed belong to Paul Stanley. This interesting pre-makup removal era photo has recently surfaced and is quite an unusual image to behold.
As our friend Scott Davis pointed out, it is rumored that this photo was taken at the Park Avenue Methodist Church at 106 E 86th St, New York, NY. This is not true, as the door was a studio prop built specifically for the photo shoot. The front door of the Methodist Church does appear to be identical, and was most likely used as the model to construct the prop. You can see the Church on Google Street views below:
