We found this box of old (definitely) non-LEGO bricks in Czech Republic. Probably from the seventies or eighties? Does anyone know the manufacturer - brand or set (s) from which they can be? We thought it was Wundersteine (Wonderbricks), but their bricks are different. Here are some photos, no visible logos. Many thanks for any suggestions.
This is one of Eastern Germany's (DDR) two brick systems (created by typical VEBs and I'd be suprised if you find those letters anywhere printed on the bricks):
- most likely Formo because of the simplicity of the backside and how basic all the bricks are - you should not be able to combine it with Lego bricks and these bricks are rather difficult to impossible to assemble. Or
- less likely PEBE because I've never encountered so large bricks for that, and in your pictures I see not one specialized brick although those weren't uncommon, while sets with only basic bricks were not typical - you should be able to combine it with Lego bricks and these bricks can be put together without further problems.
PEBE's bricks looked different thru the years - what you show might be from 1980s, because later the studs consisted of cylinders only (yet still compatible with Lego). For i.e. 2x4 flat bricks without studs it was very typical to have not even one cylinder or stud on the backside.
Formo's highlight was a set of the Palast der Republik, intended to be bought as souvenir.
