It's Lübke, a German manufacturer.

I had a couple of Lübke chairs in the past. They are indeed very similar. But I think mine are not from Lübke. The shape is slightly different and Lübke has usually a plastic sticker underneath, that usually not fall off. On my chairs there is no mark or sticker.

Lübke has manufactured a lot of different chair designs in the fifties, seat and legs mostly similar, only the backrests were different.

I can't prove it, but I am pretty sure it's Lübke. If not ... I would like to be told otherwise. 😀
