Hindsight suggests that I didn’t have nearly enough time to play with blocks when I was a tyke. And it’s equally clear that Agincourt has afforded time to remedy that deficiency. I suspect that “retirement” will permit even greater exploration of building systems in general and examples like Fröbel and the set you see here (on the left) from “The Village Blocksmith“! — whose products I show as apology for doing so without permission. If any readers know other similar sets, please pass your recommendations along.
