The Gonzo Photo Puppet Replica is on sale for $99 with free shipping right now.
I ordered mine a couple of weeks ago and he is amazing. Having had the privledge of seeing an actual Gonzo photo puppet poser up close *and* also seeing the actual Gonzo puppet up close (along with Dave Goelz), I can tell you that this is a wonderful reproduction. It probably the closest thing to owning an actual Muppet that will ever be made available. $99 is a really good deal (it retails for around $200).
The Photo Puppets (or posers) were/are used for still photography. If you remember the old Muppet Magazine with the pictures of celebs with the Muppets, all of those pictures are with posers.
