Signature

Not all art is signed.

A lot of art is signed with what looks like "NBEN", rotated 90 degrees. If you inspect the signature closely, though, the "N" is actually an "r" and a "u", making "ruBEN". Both "N"s are done this way, so it can be read with either end up. 2003 example here.

There is one post here that has a signature with vertically stacked and split letters that might be "MANTIS". The "00" at the end is probably 2000. (There is one post on VCL that has a similar "MANTIS 99" signature, presumably from 1999.)

In 2001, the signature often read "ruBEN 01". For 2004, 2005, and 2006, the signature would have a number of dots at one or both ends; the total dot count was the last digit of the year. This seems to have been discontinued in 2007.
