70s vintage Nestle's Rich N Creamy Hot Cocoa mugs, retro font advertising graphics

Pair of 1970s vintage Korea ceramic mugs advertising Nestle's Cocoa. These are a bit under 3 1/2" tall.

Both are nice and glossy inside and out, though the color is uneven on the interiors. Looks like glaze coloration, not staining. There's no chips or cracks to either of these, but one has a little wear to the rim.
