Measures about 13 1/4 x 5 3/4 inches. Pictured in "Griswold Muffin Pans" by Jon Haussler on page 131.
At the time this book was published in 1997, it states that only 3 or 4 of these pans were known to the collecting community. Great condition with no chips, cracks, rust or repairs. I have not cleaned it in any way. I'm not terribly concerned if I sell this, as reflected in the price.
