Keith Haring and Dan Eldon both used art journals to document their lives and ideas. Haring used his journal as a bank for sketches, notes, and reflections, documenting daily life in a less personal way. Eldon filled his journals between ages 15-22 with collages, photos, drawings and ephemera, documenting his travels and using satire as commentary. He considered his journals personal works of art, while Haring saw his as a useful tool. Both artists represented concepts in their work and left their mark before passing away at young ages.
