I like it too, but (without looking for another image of the actual race CSLs) it seems this rendition is lower to the ground than actual, and the tire size exaggerated.
This is my desktop. The car that started my love affair with BMWs over 40 years ago. Then reunited at Laguna Seca in August 2016, pic by Peter Coomaraswamy. The Calder car is the same CSL that Hans Stuck got famously airborne on the Nurburgring, we all know that picture.
My good friend Joe Rodriguez has a tribute street legal Stella Group 5 3.5 CSL in BMW Works trim with an S38 built by Jack Derrin. The car is an absolute blast, it's so fast and sure footed.
I never knew!
