This rare trio of mid-Century OTK folding chairs  originate from Czechoslowakia and are uniquely shaped with an oval design.  Made of steam-bent beech wood, these chairs are larger in size than other folding chairs yet they fold flat as shown, for easy storage.
Condition is remarkable for age - each chair is stable and sturdy and generally in a good state with some scrapes and scratches commensurate with age.  Each chair is stamped with the circular OTK logo with the model ID 27.
