this picture has already been posted in the forums. we have established that this is not peter criss, but another drummer who looks just like him. i forget his name but he is also the actual drummer on the album, as well...

This is, again, NOT PETER

The drummer as listed on the back cover is Don Poncher who bares a resemblance to Peter Criss.

As kiss0l0gy stated above, IT IS NOT PETER CRISS.

Thanks you ros, yes it's don poncher. You can google image search him. Even in the early 70's, the photos of Don Poncher look like peter in the chelsea/albatross/lips era. They had matching facial hair throughout the 70's. But it's a total coincidence.

Wow, this is a Peter lookalike? The resemblance is uncanny

It's a little known fact , but for a long time it was supposed that it was KISS drummer Peter Criss on the photo (center) without his famous "cat" costume and make-up, though Peter Criss denies it was him. He was credited as a drummer named "Ming The Merciless" even though he didn't play on the album. None noticed back then, until 2002, after it was mentioned in the KISS Book "Alive & Forever" (by Curt Gooch and Jess Suhs).
In 2012 Michael McKean responded on his twitter that "Peter Criss was nowhere near this project. The drummer (on the photograph) is Don Poncher, aka Ming the Merciless".
Lenny and the Squigtones is a musical group composed of Michael McKean and David Lander, the two actors who played the characters Lenny and Squiggy on the television series Laverne & Shirley. The group's eponymous debut album, Lenny and the Squigtones, was released on the Casablanca label in 1979. Otherwise forgetable, the album is now a collector’s item because of credited guitar work by future Spinal Tap member Nigel Tufnel (Christopher Guest). Included an early version of "Heavy Duty", which was later recorded by Spinal Tap. Also includes 'Murph', the keyboard player from The Blues Brothers.
