I've been trying to work out whether the boy in the 5404 diorama is begging. If not, I guess he could be in charge of selling the paintings which are lined up against the fence.
I think your second guess is right - he's the artist's son, in charge of sales while his dad continues painting.
Wonderful detail those dioramas, lots f charm and character, and I wish I'd bought some at the time.
I like the two Policeman shots - just one figure has been changed, but the ceowd are all the same! I guess French and German civilians in that era dressed much the same?
Is it too much to hope that Playmobil might re-release some of these sets as an Anniversary celebration, as they did with some Western sets? I'd especially love to have some of those children with their toys - the boy with a paper hat & the toy cannon is a wonderful piece!
