I used an old photograph of a cemetery on this piece as well as text from a liturgy that says "a vow". Then hand-wrote in Russian:
Sonia's letter to Nikolai, which was the realization of his prayer, had been written from the Trinity Monastery.
He is now free and clear to pursue Princess Marya. -- Lola
from page 437-438, volume 2 of original text
