Dear Colleagues,

I am trying to check on permissions for an image (a black & white drawing) I'd like to reprint that came out in an edition of the Caraka Samhita with Shri Venkateshwar Press in 1898.

 

I wrote to the press using an online contact form at the Khemraj Shrikrishnadass website, but received no response. 
Does anyone on the list have a contact at this press who might be able to help me?
 

Also, re copyright laws, does anyone know if after a certain number of years an image in a book becomes part of the public domain?

 

Thanks in advance for your assistance.

 

All the best,
