i love light on black art.. especially that pull-down chalkboard map from Restoration Hardware but it's most definitely out of my budget. *sigh* someday... maybe. How fun would it be in a kids room?! (though I suppose you could easily DIY a chalkboard map on a wall with paint)
left to right, top to bottom: pull-down U.S. chalkboard map, California flowering trees print by Claire Nereim (i adore all her work), Dr. Auzoux chalk plates from Room&Board (also quite pricey but so lovely).
