This Pyrex HTF Pink Butterprint casserole set is an original, mid-century modern classic produced as a promotional set from the late '50's to early '60's. The three dishes are sizes 1pt. (#471), 1 1/2 pt. (#472), & 1qt (#473) and two come with a lid. These bowls have never been in a microwave. The graphics on all 3 are factory crisp, very clean and clear. There are no chips or fleabites and the bowls have very few tiny utensil marks. Almost factory fresh.
