Thanks for sharing the pre-Playmobil pictures.
I guess someone in the design department was obsessed with phones...
"Helleu, diz iz jiev-inspector Cloustättereau zpeakin on the pheurne"
On the third-last photo, I see in the righttop tiny jetfighter models of a 1950s F-86 Sabre (or is it a MiG-19?) and a 1960s F-4 Phantom II ... if only they would produce that as Playmobil too.
edit: when enlarging the photo, I believe the fighter-models are an F-100 Super Sabre and a F-101 Voodoo
