The reason you don't see Sam in the other present-opening pictures is because he was standing in the back being a guitar
Two of these guitars have their own web pages on my site:
My Martin "Backpacker" travel guitar
My Fender Venus
You can also see a larger picture of my Liberty "Shooting Stars" resonator guitar here.
p.s. The upside-down guitar on the top is actually a clock -- the neck swings back and forth as the pendulum.
