Not really wishing to continue this whole ground textures debate, however I was looking through one of my Ju-52 reference books when I came across a 1/2 dozen or so postcards that I forgot that I had, I purchased these a few years back after having the great privilege to go on a Ju-Air flight.
One of these post cards in particular caught my eye and I just had to scan it and post it here, if you can ignore the rape-seed crops you may notice another distinctive crop colour, that apparently does not exist?
Yes I know it’s a fairly modern image, but I felt it may be relevant none the less, flame-on kiddies.
