This is a vintage Glasbake-divided ovenware casserole bowl J2352.
The 2-section white bowl is in the "Currier & Ives" pattern, dated 1950-70. It features a couple riding in a horse-drawn sleigh through the snowy countryside.
The bowl measures about 8.5" wide, 12" long and 2" deep.
It is in pre-owned condition with tiny chips by one handle.
