I'm no expert on MCM furniture, and don't know a whole lot beyond Eames and Barcelona, but I saw this chair in a magazine and sort of fell in love with it. Unsure if it's a canonized classic or just another design, and I don't know if the designer is a household name. Just know that I like it and wouldn't mind having one (or two ), as long as it's not outrageously expensive. It was attributed as the Costela chair by Martin Eisler. I found some store in Brazil that shows it on their website but I'm not convinced they actually are selling any - seems maybe they're just advertising they can service it? Image is peeled from their site (Loja Teo).
