Vintage Mixing Bowls (Each)

We bought these super bowls on separate treasure hunts, but they seem so complimentary - perhaps because of their similar size? Or the fact that this kind of bowl is so handy in the kitchen? I'm not sure but they are both in great condition and really lovely! The blue bowl carries its much faded maker's sticker at the rim, and I can't figure much from this (if the sticker shape is meaningful to anyone out there, please do share!). The milk glass white bowl, carrying the cool rust brown flower image, belongs to the American brand, Federal Glass - a company that has produced many wonderful ranges of glassware in their 80 year history (the company sadly closed down in the 1980s).
