The stylized, script "N" signature near the base confirms that this mug was illustrated by artist Win Ng for the iconic Taylor & Ng company based out of San Francisco. Win Ng was a prominent mid-century Asian-American artist, sculptor, and co-founder of Taylor & Ng. His distinct, loose line illustrations and whimsical doodles became the definitive style signature for the brand's wildly popular kitchen collections. This specific doodle-style blue flower pattern belongs to their line of hand-painted, casual kitchen ceramics produced primarily during the late 1970s and 1980s. Because most collectors search for Taylor & Ng's screen-printed character mugs (like the famous penguins, cats, or whales), these distinctly hand-painted floral art mugs signed by Win Ng are much less common on the secondary market. Individual mugs from this signature artist line typically trade for $20 to $35
