This is a ceramic mug with matching coaster or lid and infuser or diffuser with a motif of a swan in a blue and white design from a group of wildfowl mugs called called On The Lake.
The mug measures 3.75 inches high and was made in 1999 in China by Design Wyrkx for a division called Hues 'N Brews for Herman Dodge, USA who closed in 2009.
Cute and handy all-in-one!
