Jeff,
To the best of my knowledge there is not. My Great Grand Father was in Company F. They did have at least one reunion that I am aware of and it was held in Chicago in 1871. That was the same time as the Chicago Fire. perhaps there is a photo of them take then. If you find one, I would love to have a copy. By the way there will soon a book out about the 90th by Jim Swan of Nashville. I am planning to have coffee with he and his wife Pat on the 11th of this month when they visit my home town. You can find some pictures of members of the 90th at the Illinois in the Civil War website if you are interested.
Do you have his muster in record? It is available at the Illinois Secretary of State website if you don't.
HOpe this helps.
Frank
