Congratulations Moritzamica, you found very accurate prints of old Jelcz. It is not easy; while you can find many Jelcz prints in the net, finding accurate print is a real challenge! Thanks.
P.S. hard to say, if it is really 1958 model year. It has Skoda emblem on the lid of cooling fluid reservoir and it is correct, but it has rectangular turn signals (blinkers) and contour lights, which were mounted in later series. Never mind - Great print!
