Harry Nielson's 1917-19 Biology & Hygiene Notebooks with Tons of Diagrams broccoli and row of potted tulips

and row of potted tulips on the shelf at right

I just can't resist naive floral watercolors like this one

cut and pasted from a catalog I guess

There’s barely a centimeter of this antique toy slingshot that wasn’t decorated with hand-carved designs: leafy vines all over

Harry Nielson's 1917-19 Biology & Hygiene Notebooks with Tons of Diagrams broccoli and row of potted tulipsI really love these high school notebooks, kept by a Harry S. Nielson in 1919 for biology and hygiene class, with lots and lots of primitively hand drawn diagrams, which I find immensely appealing and almost make me want to the subjects such as "how to locate the boiling point" and how magnets work. My favorite is a section off charts diagramming the proportions of water, protein, fat, carbohydrates and ash in various foods, from dried figs to bacon,
