I've seen (and played) a few of these ~ one of them prominently displayed at the Martin factory which I toured a year or so ago, stopping off during one of my many drives back and forth between New Orleans and New Jersey.

This is just one of a series of playfully-designed small Martins made of all-synthetic materials ~ "laminate" instead of regular hardwoods. I suppose it's easier to accept all that cartoon decor (paint and/or decals) when you know it's applied to a manmade surface, not desecrating real rare woods.

They seem to have a nice bright tone and surprisingly loud sound. As good clear tonewoods and topwoods become increasingly rare ~ as the available stock gets used up ~ ever-increasing use of these new materials in the manufacture of moderate-to-good quality stringed instruments is probably inevitable.
