Journals and Notecards

The images above show a small sample of Jan’s Notecards and Journals. Jan was prolific and constantly had ideas that he would capture through various methods that included journals and notecards. The journals shown are from the 1950’s. The notecards were used as a later methodology to catch his observations that were more flexible and would allow him to be lighter when he was on the move. They would fit in his shirt pocket.
