Got these in an email the other day. A bit different.
Yes it is the same truck in each photo. 
ta very much , a nice selection of advertisements ,which is really growing
and does show us in a better light to the public at large.
col, they look great mate, 3d!
Brilliant, but are they really such a good idea? You can imagine drivers’
attention being diverted in fascination rather than keeping it on the
road 
.
Someone posted a couple of these earlier and I didn’t realise what they
were 
.
Salut, David.

Salut, David.
Those trailers are participants in some kind of contest. Winning trailers were made “real” by hooking some kind of painting into curtainsider. At least this is what I think as my linguistic abilities halt when I see german text 
Real pictures can be found here.
They look really good

Didn’t notice, did realise they were fakes though, very interesting nevertheless
IF I have read the german text correctly these pictures are showing a new method of advertising it seem that certain firms have put their form of advertisment onto the trailers side ,this is a new type of advertising which is inpractise in Germany ,inthis case this was a competion to find the best advert which when chosen would then be then placed on the sides of trailers,
yes the photos were pasted on in this case ““BUT”” this is a new form of useing the trailer as advertiseing space,
and is in use in GERMANY now,
