<p style='text-align: justify;'>A letter (probably 11th century) in Judaeo-Arabic has been reused for writing exercises. Only the end of the exordium and the transition to the main subject matter of the letter has been preserved. It addresses a dignitary and refers to the honouring of his name at the festival of Purim, but goes on to talk about Passover. Verso consists of alphabetical writing exercises in a cruder hand, the alphabet forwards, backwards and in atbaš. Some of the writing exercises spill over on to recto. </p>
