This is a set of 4 demitasse cups and saucers made by Warner Brothers with Looney Toon Characters. These were made in the 1990's and come in the original box. They are in excellent condition with no signs of wear to the gold on the handles or designs, however one saucer has a small chip on the rim  (see last photo). The plates are 5 inches and the cups are approx. 2 1/8 inches tall.
