The term refers to bike parts engraved with the builder's (or other's) name. Take a Campagnolo chainring, engrave it, and you have a 'pantographed' chainring.
A pantograph is actually the tool used to copy the pattern from a master to the part being engraved.
A question I've asked, which might be a bit irreverent, is what's the maximum number of un-matching pantographed parts you could build up a bike with? And who's done it?
