These happy whimsical illustrations are by Janice Jong, who seems to have a fascination with cities. Illustrations are hand drawn, scanned, then colored in digitally. I love collecting art, especially illustrations so this is right up my alley.
For a second illustration,
She seems to concentrate on cityscapes, but below is an illustration of just chairs of all proportions. The artist takes inspiration from architecture, city life, mixed with a splash of fantasy, hence the whimsy. They seem to draw you to look deeper. I get a sense that someone will appear all of a sudden.
Pricewise you're looking at a very reasonable purchase. There isn't a huge selection but what is there is satisfying. Contact the artist to see if she'll do a particular city in a particular color, I'm sure she's open to suggestions.
