From the Vatican online archives

The icon, probably brought to Rome from the East, was already mentioned in the Liber Pontificalis under the entry for Pope Stephen III (752-757). A full representation of the enthroned Saviour, it was painted on cloth applied to a wooden tablet measuring approximately 1.52 m. by 70 cm. The icon has been frequently restored, most recently in 1995-1996. The only part presently visible is the Face of the Lord painted on a silken cloth superimposed upon the original. The rest of the icon is covered by a sheet of silver.
