Sets like these are generally 1950's Continental pieces, loosely based on 18th Century French and Italian Rococo furniture. Most of it tends to be good quality with more hand crafted detail than one would find on North American pieces made during the same period. Highly decorated painted furniture is far more popular in Europe than in North America. The last two periods of popularity for furniture of this type in North America was the during the 1920's and the late 1950's. Rococo furniture has come in and out of style many times, in the 1850's, the 1890's, the 1920's, the 1950's and again in the late 1990's.
Values for furniture like this depends a lot on the condition of its painted decoration. Painted furniture, with it's extra layer of protection from season humidity swings tends to resist damage such as warpage and cracking that pieces with thinner clear finishes experience. Care should be taken though with some furniture cleaners which can soften the paint or fade the color. Make sure any polish used is listed as safe to use on painted surfaces.
Demand for furniture in this style is currently not in vogue, but it did have a brief run up in values in the 1990's. Values for suites comparable to this one remain modest at this time with similar suites selling at auction for less than $1000.00.
