What about the Multiplier of Wheat icons? They don't show Christ.
Not only is Christ absent, but the Mother of God is shown in a blaze of uncreated light.
From the "Canonical icons" thread:http://www.orthodoxchristianity.net/forum/index.php/topic,17565.msg305661.html#msg305661
The Multiplier of Wheat shows the Mother of God surrounded by a mandorla, an oval motif of rays and stars which represents the uncreated light and glory of God. This is a major error in iconography, as the Virgin, while, of course, partaking of the glory and life of God, is not divine herself. She does not generate this light. Christ alone may be depicted in this light, such as in icons of Christ in Majesty (Christ enthroned, surrounded by the bodiless hosts), the Transfiguration, the Dormition of His mother (where He is seen holding her soul in the form of a babe in swaddling clothes, surely one of the loveliest of iconographic motifs, and truly loaded with theological meaning), and in icons of the Mother of God of the Sign, where He, as Christ Emmanuel, is surrounded by a circular mandorla over His mother's body as she holds her arms raised in supplication. By contrast, a mandorla is often seen in western images (paintings and statues) of the Virgin, notably in Our Lady of Guadelupe.[/i][/color]
The post I linked to also has something to say about other, similar images, and how they can be made to conform more closely with Orthodox teachings and proper iconographic tradition.
