AbstractWe report the discovery of another IRAS source (22574 + 6609) showing the unidentified 21 μm emission feature. Its overall energy distribution is similar to the well-known edge-on bipolar nebulae AFGL 2688 and AFGL 618. Ground-based optical and infrared observations of this object and two other 21 μm sources show that while all three have very similar infrared properties, they differ greatly in the visual region. We suggest that all three of these 21 μm sources are intrinsically similar bipolar nebulae viewed at different orientations.
