These are very nice (48)-page cardboard-bound notebooks with themes and some unobtrusive notes/formats that will be easy to ignore if you’re not into the subject, but twice as nice if you are. You pick: the 3-1/2” x 5” Mister Rogers’ Neighborhood-themed passport/notebook, issued by King Friday XIII, with a drawing of the castle and trolley on the front, a larger trolley on the back, and (7) Mister Rogers traveling tips inside; the 5” x 7” Stargazer’s Notebook with 1/4” rules plus a lightly printed 3-1/4” dia circle with 30-degree markings to chart the sky, and a fold-out back cover with an astrolabe and constellation chart; the 3-1/2” x 5” Entomology notebook with a beetle cover, fold-out back cover showing a metamorphosis of an adult insect, ruled pages and room for observational notes and sketches; or the 3-1/2” x 5” Botany notebook with a fold-out back cover with illustrations of leaves for identification, ruled pages and room for observational notes and sketches.
