Beautiful Vintage mugs with colorful bottoms & each depicts a different species of bird on each cup. Mugs are footed & have a handle. Red bottom mug marked Japan on the bottom. This is a set of 2. Yellow & Red bottoms. Most likely Fred Roberts mugs from the 60’s. Each mug measures approximately 5.50" high & the opening is about 3.25" across. Holds about 9 fluid oz. Good condition with some minimal wear. The yellow bottom mug has a small stain on the bottom that may come off with further cleaning. It can’t be seen unless you hold cup upside down. Red bottom has two tiny black marks on it’s bottom. Again these are from normal wear & could be cleaned further. See all pictures up close for more detailed views as the pictures are part of the description. Beautiful colorful set! Wonderful gift! Nice to fill in a set you may already have.
