Ups I didn’t see the attachment Wesbach posted and that’s a good one, so here is more:
It’s “not even similar” to the semi-script signature shown here on findartinfo in signatures of the artist. As to the other print type signature that can be seen on some of his works; well, how different Latin print letters could be in principal? But if you look careful enough you could see the difference especially if you look at a number of samples so you could see what changes and what stays the same and there fore distinguishes writing of a particular person. At the sample of sig’s that Wasbach attached look at the most obvious differences; letter “o” note where it starts and where it closes (top/bottom), letter “n” last stroke top to bottom vs opposite, letter “a” decentralization (right/left), letter “L” one-stroke/two-strokes course etc.
So in a way those signatures are very different as well.
