A set of two glass-lidded refrigerator dishes in the "Butterfly Gold" pattern from Pyrex.  The larger dish measures 6 3/4" across, 4 1/4" wide, and 3" high.  The smaller refrigerator dish measures 4 1/4" across, 3 3/8" wide, and 3 1/8" high.  The large dish is marked "0502 1 1/2 PT. Trade Mark 30 PYREX Made in USA Ovenware."  The small dish is marked "501 B 1 1/2 cup PYREX Made in USA 15."  The condition of both dishes is very good, with bright clean graphics with no scratches or hint of use.  There is a small area of roughness to the edge of the glass lid on the small dish. 

Corning Glass Works and Pyrex

From Wikipedia:  Pyrex was created in 1915 when chemists at Corning Glass Works invented a new kind of borosilicate glass that could withstand extreme temperature fluctuations.  Soon after, popular over-to-table-to-refrigerator household kitchenware was introduced.  The continued popularity of Pyrex over the years saw the creation of nested and Cinderella mixing bowls, casseroles, divided servers, refrigerator sets, carafes, and dinnerware (to name a few) in bright colors and lively patterns.
