Hi Gerardo, I don’t know about the first one, but regarding the second one, I found this, which looks practically identical: https://www.origami-resource-center.com/birkeland-butterfly.html <https://www.origami-resource-center.com/birkeland-butterfly.html> and is attributed to Hans Birkeland. Even here, the attribution is uncertain, but at least it might give you a lead… Thanks, Matthew
