I have made a few Artistamps of good ol' Art Tower (Cousin Arty to me) over the last few years - from snaps I took when he visited me here, in the 4th Dimension. Here, he seems to be bubbling with joy (Opti-Flux).
I hope your show was a successful one. I sure wish I could have attended. Ah well, anyway, thanks for the card my old friend - I miss you and I'll see you in the mail. Arttower's Mail Art.
