I'm way past the generation that played with Legos. Actually my grand children played with Legos and some one told me they were...Legos. The color attracted me.
Great find and nicely photographed. I am a few years younger than you, and one of my favorite memories as a boy was visiting the original Legoland in Denmark circa 1962. By that time I was already getting nothing but Legos for my Birthday and Christmas. I think they were popular for decades in Europe before they caught on in the U.S.
