To Mrs. J. M. Mozart 
The undersigned, wishing to testify their appreciation of your merits as an artist, and their most perfect satisfaction with the concert given by you on last Saturday evening, respectfully request you to give another entertainment, similar in character, on your return from Jacksonville.
Your most excellent treatment of those sterling songs and ballads, has left a deep and lasting impression on those who had the pleasure of listening to you, and created an earnest desire to hear you once more before you leave the West. Trusting that your engagements will permit you to accede to our request, we are, dear Madam, your most obedient servants,
 Illinois State Journal, January 11, 1859. Lincoln's name appears as one of fifty-two signers, omitted for reasons of space. Mrs. Mozart's letter of January 10 acceding to the request to give another performance before returning to New York, is also printed in the Journal. Her first concert scheduled for January 6, was postponed because of inclement weather until Saturday, January 8, and in response to the above letter she sang again on the night of Tuesday, January 11 at Cook's Hall.
