Woodland refrigerator sets are often hard to complete because they existed for such a short time. Although the pattern was marketed 1978-1983, refrigerator sets were discontinued mid-1981. Finally found the 503 to complete the set today for $10 at the same place I found the Earthtones 933 lasagna pan. Gathering the pieces together for the photo, I realized I had accumulated three 502s and four 501s in the interim.
