Cordatic forensic

I wanted to illustrate Cordatic, a defunct brand of tyres from Hungary, here on PunchBuggy, so out came the corn starch and a small artist paintbrush, and here is the result. Watching all those crime investigation shows on TV had to be good for something.
These tyres are still rolling after more than forty years and long may they continue. They are survivors from an era when made in Eastern Europe was hardly a recommendation - remember all those Skoda jokes - but they must have been doing something right.
P.S. The tyres on my Auto-Mini bicycle have the (batch) number 9 _70/4. Presumably manufactured in April 1970. Now coated with Meguiar's Hot Shine Tire Spray - its says "keeps your tires looking blacker longer while preventing cracking, browning and premature aging."
