This is Mark's most complex air trap style, with controlled air traps all up and down through the marble. The final effect is just awesome. This is one of his earliest takes on this Super Jetson style, created clear back in 1996 - it's almost 2 decades old now, which is VERY historic in the world of art glass marbles! In hand it is killer, SO much better than my pics. Mark really set the bar high for airtraps, the originator of the complex designs, and he still reigns supreme all these years later. Don't miss this awesome piece of art glass marble history! Signed 'Matthews 1996'.
