Folk artists have long used bottle caps to bring texture and color to their works, and Gregory Warmack, or "Mr. I," as he prefers to be called, has taken this practice to a new level. A native Chicagoan, Mr. Imagination began to carve figures from found pieces of industrial sandstone (a by-product of steel manufacturing) during the early 1980s. As his work attracted attention, he began to use another salvaged material-bottle caps-toward the end of the decade. Warmack excels at turning discarded materials from the streets and alleyways of his hometown into art, and transforming the castoffs of contemporary society into celebrations of his unique identity.
