2 Vintage Enamelware Flower Pattern Bowls Daffodils

2 vintage enamelware bowls, spaghetti or soup bowl shaped, with daffodils or sunflowers in the center and green ribbon drapes and cobalt blue rims. They are marked Bon Voyage Made in Shanghia China and S06-113-22cm and some other words I can't make out. They measure 8.5 inches in diameter. They are in good used condition and one has a small chip on the inside bottom about the size of a grain of rice. They both have metal utensil marks that look like they could be removed if you knew what product to use to remove them. These look like old items but I don't know the age for sure.
