If you’re old enough to remember clip art, you may have invested in some of these too! I’ve got an entire bookshelf full of copyright-free reference archive books. As I divest myself of my worldly junk, I wonder what to do with such book collections! But they are entertaining and interesting to flip through, and the art is highly usable for anyone still in the design or marketing fields. Some of these pieces are beautiful — far more beautiful than you could develop at today’s rates! They also make excellent idea starters! Enjoy!
