Pattern: Friendship
Identifiers / Alternate Names: Colorful orange and red bird motifs on white background form the basis. Some casserole lids are clear with the pattern, others solid white, but both have the birds in a circle. Some sets also include solid orange and red colored items with no bird pattern on them, though sometimes combined with lids that have the bird pattern. NOTE: Do not confuse the popular 1975 Corning Ware pattern known as Country Festival with Friendship! Though the pattern is setup similarly, the birds are Blue on that one and this is NOT the Friendship pattern. Also known as: Birdie, Friendship Bird, Pennsylvania Dutch Bird Scene, Red Rooster

When we first started collecting Pyrex, we had mistakenly thought that we had a #503 Friendship pattern oven-refrigerator dish that was orange when it was actually part of the Daisy line that we had. This set has the usual 4 rectangular pieces: two #501 1.5 cup dishes, a #502 1.5 pint dish and a #503 1.5 quart. All of these have clear lids - we believe they are the ones with lines going all the way across. The two smallest were orange color bases, the second size was a red color base, and the largest size was opal white with the Friendship pattern along the side in orange and red.
