Tweet Design sends out these great promo cards every month with that month’s calendar. I helped out with a series that assigned a month to invited guest artists.
 
The illustration is based on T.S. Eliot’s poem The Wasteland.
 
April is the cruellest month, breeding
Lilacs out of the dead land, mixing
Memory and desire, stirring
Dull roots with spring rain.
 
Diamonds are a girl’s best friend and the birthstone for April.
