Four Bas-Relief Figural Decorative Plates

This is a set of four decorative plates, likely ceramic or porcelain, featuring bas-relief figural depictions of historical or literary characters. Each plate is circular with a raised central image surrounded by a painted background scene. The figures are rendered in a somewhat comical and exaggerated style, with bold colors and defined outlines. The plates appear to be hand-painted, with visible brushstrokes and variations in color application, particularly on the background elements like trees and sky. The bas-relief is prominent, giving the figures a three-dimensional quality. One plate depicts a stout monk-like figure holding a jug and a piece of food. Another shows a man with a long white beard and mustache, wearing a green outfit with a sword and holding a goblet. A third plate features a man in a tri-corner hat and naval-style coat, holding a bottle. The fourth plate portrays a gentleman with spectacles and a top hat, adjusting his hat and wearing a suit coat. The overall condition appears to be good with some apparent patina and possibly minor wear commensurate with age, though no significant cracks or chips are visible in the provided image. There are no discernible maker's marks or signatures visible in the images. The style suggests they could be mid-20th century production, possibly by a studio pottery or a manufacturer specializing in decorative ceramics. The quality of the craftsmanship appears decent for mass-produced or semi-mass-produced decorative ware.
