While in the Reuther Library this year I found a newsreel [[not available online to my knowledge) from The Detroit News showing the construction of the old YMCA. In particular, the reel features the laying of the cornerstone and the placement inside of a time capsule. Was this forgotten and lost during the demolition or was it salvaged?

I've also read that a capsule was placed within the Soldiers and Sailors monument and recovered, but couldn't easily find details.

What about other buildings? With so much demolished, I wonder if other capsules await discovery, or have been accidentally lost.
