Earlier this week, we explored 7 essential books on street art. If you’re ever fostered fantasies of spraying down a center-city building a tag of your own but never gotten past ogling the spray cans at Home Depot, then there’s a middle-ground oasis for you. Enter Walls Notebook, a charming activity book (and a fine addition to our favorite coloring books for grown-ups) that invites you, armed with a Sharpie, to unleash your inner graffiti artist on irresistibly inviting blank-slate urban walls from around NYC. It’s part Stencil 101, part Trespass, part playful new way of making street art more than a spectator sport.

The brainchild of NYC-based photographer and designer Sherwood Forlee, Walls Notebook is an absolute treat, reminiscent of Kerri Smith’s fantastic activity books for grown-ups.
