Hello dear Mr. Sans,  We have four Welte rolls (Red) from pianist
Teresa Carreno :

No. 363  Fantaisie de R. Schumann C-dur Op 17, recorded April 4th, 1905.
No. 373  Sonata de L.v.Beethoven Op53, C -dur Waldstein, no record date.
No. 365  VIeme Rhapsodie de Franz Liszt, no record date.
No. 371  Petite Valse de Teresa Carreno played by herself, no record date.

Of course we'll be happy to join you for planning some special event
for this celebration.  We own these rolls and of course the
Welte-Mignon to play with.  I don't know if four pieces are sufficient
but we can try to provide you others.
