The origin of these eggs were bugging me, and tahra left a good lead......
I went through the Playmobil Collector guide and I finally found something on page 444. The two eggs shown on the first post were part of a serie of 3 different eggs that were given in 1998 on "Open Factory day"......
The last thing to know is the "Open Factory day" of what? I would guess it's Fun Park in Germany... In fact like tahra mentionned there is a sticker on these eggs that says
"Tag der offenen Tür" & "Diettenhofen 16.5.98"..... Can somebody translate that?
How the hell did I get my hands on those eggs? I don't have any idea... I for sure wasn't there on opening day in Germany!
Well, it's great to eliminate some clouds over these eggs...
I leave you a scan of the page in the Playmobil guide...
