Civil War Muster Roll

I have a photocopy of a Civil War Muster Roll which I am not sure where I got so I am having trouble with how to write the source citation. The document looks like a photocopy of a ledger book, with the names of those mustering in to Company A 87th Illinois Volunteers. 

I know that I made this photocopy from the original book, I just don't remember if I did it in Salt Lake City at the library or in Illinois at the state archives. I did it way back in the early 90s when I first started researching and did not write down any source information. 

I would appreciate suggestions on how to write a source citation for this document. Thank you!

Ah, yes, the Ghost of Research Past-Imperfect does haunt us all.  As a placeholder, until you locate the record again, EE would recommend citing it as an artifact in your private possession. Just describe what you see, and state what you recall about the manner in which you obtained it.
