Vintage Otagiri sailboat ceramic mugs

Two collectible and sought after, vintage 1970s, hand painted stoneware, nautical mugs. Sailboats, birds, rainbows, waves, clouds… what more could you want?! Perfect for any sailor, collector, or anyone who just loves harbor seascapes! The mug with the rainbow on it does have a visible crack on the backside… However, I have used this many times in the past and it has never presented an issue, no leaking, etc. But please see pics! They stand a bit taller than normal mugs. About 5 inches tall.
