SPW-251 artwork variations

[Bluebell88A]

I just noticed that several games have an SPW-251 image that is similar to an SK-7:
Road To Berlin - countersheet 2 front (but countersheet 4 rear has the correct image) (2005)
Elsenborn Ridge (2008)
Fall of France (2009)

Correct images are in:
Battle of the Bulge (2002)
Beyond Normandy (2004)
Eastern Front (2005) - uses countersheet 4 from Road To Berlin (2005)
Kursk South Flank (2012)
Liberation 1944 (2013)
Kursk Burning Tigers (2014)
