Waechtersbach Groovy Vintage Mug Manufactured in West Germany

Alternating baby light blue and light orange dandelion wavy lines give this mug a major 70s vibe! The shadows are not painted, they are acual small grooves in the mug. About 3.75 inches tall. Extremely clean! Was manufacured with a tiny bubble in the handle, pictured. Tiny mark on the bottom; otherwise, I can't find any flaws
