Hey, I would use this pen we carry at 
Michael's...it's manufactured by Sakura Color 
Products Japan and made for marking on the backs 
of photos. It dries really fast so there's no 
need to worry about smearing. It might not work 
for much finer lines, although it does have a 
"fine tip".

Heh, I see we have similiar tastes in email 
addies! Heh! Actually...I wonder if you were 
thinking of the same Goemon. Probably not.
