After soaking some recent Austrian stamps and sorting them I noticed there are 2 types of the 2006 Michael Schumacher stamp.
What brought it to my attention at all was the fact that one had inscriptions on the bottom (designer and date) and the other none.
The 2009 Scott does list two types,
# 2076 issued December 4, 2006 and
# 2103A issued May 29, 2007

There is no mention about the inscription but Scott states that
No 2076 is inscribed Weltmeister 1994 1995
Scott 2103 is inscribed "Weltmeister 1995 1996 " and
has a thicker signature and greyer hair.
Designer and date added to later version.

Michael appears to have aged in a matter of 5 months

Strange that the Redrawn type has the
wrong date since Schumacher was the Formula One driving champion
in 1994 1995 2000 2001 2002 2003 2004 but
not in 1996. You'd think it would be the other way around correcting
the wrong date.
Scott indicates that both were printed via photogravure but from what I can see the original was offset and the redrawn appears to be photogravure.
Amazing how much fun one can have with a couple of inexpensive modern stamps.
NB: Replaced missing images.
