In order for me to properly assess what you have I will need to know the size and see images of this lithograph and the publishers small print.
Please send the photos at your convenience. There is not an extra charge to provide more pictures here.
Thank you for the images and for your patience. Kurz and Allison were publishers of fine prints for the public. Thus, this image was mass produced and any person or institution or institution to purchase, and in this case the American market.
Your image of St. Leucadia of Toledo has a retail sale value of $200 - $300 on today's market. The suggested insurance or replacement value is $400.
