Pair of blue opaline vases from Vallérysthal Portieux decorated with roses

Lovely pair of vintage vases in light blue opaline fairground. They appear to come from Portieux but do not bear the signature. Delicate relief decoration of buds and blooming roses all over the round body of the vase, leaves on the neck ending in a pretty serrated collar. | Dimensions: 19 cm high and approximately 10 cm deep. Note that one of the two vases is slightly smaller than the other (1 cm difference) | In very good vintage condition, see photos.
