Sometimes the smallest things grab your attention. When going through the mountain of paper at my mother’s house I came across this tiny folded piece of paper. It was an orphaned set of instructions to a long-ago lost Architector Set #12. The copyright says 1944. I searched online for any reference I could find but came up empty-handed.
Update: I did discover, thanks to Paul (see link in comments), who found a set on ebay, that the Architector Sets were designed by professional architects to encourage young people to pursue that field of study.
