I actually emailed this clown and asked if there was a mistake with too many zeros or where the decimal point was at.
Here is the reply:

"Jack,

The prices you are seeing are for EM NOS very rare vintage backglasses. They have been stored and maintained since the early 70's and some may be the last ones left on this planet. They are used as art templates to create very accurate silk screened and or digital reproductions.

Notification:

We are think about making some of the reproductons inhouse. If you are interested in purchasing one let me know the title and I will notify you when we have enough orders to justify going forward. The price will be
$500 plus shipping."

Maybe P.P.S. would want know about this? They can send out one of those famous letters!
