Interesting that the logo for The Primary School is nearly identical to that used by artist and printmaker Gustave Baumann[1]. I was just at a lecture about him today, and the speaker said it was probably taken from the International Order of Oddfellows who had some saying along the lines of "what you do with your hands, you should do with your heart".
