Knabstrub Keramik Plate?

And a good afternoon all. I have this lovely little plate with what appears to be hand painted or airbrush stenciled Cocktail glass with fruit and a mottled background. It measures 7.5" across. There is a smoke stack impressed mark on the back which looks almost like the Knabstrup Keramic mark - at least the top half of it - the lower part seems to be missing. I was hoping that perhaps someone could confirm that it is indeed the Knabstrup mark, or if not, who the maker might be and the time period. I was guessing maybe the 1930's but not sure.
Thank you as always to those who solve or help me solve these fun challenges.
