CN City bumps being uploaded to Vimeo by a production member

Recently, I have just discovered on Tumblr that a person who has worked on the Cartoon Network City Bumpers (Geoff Valent) has been uploading them to Vimeo.

I have no idea (as of writing this) if any of the lost bumps have been uncovered by him or are in his possession.

Twitter conversation between Geoff Valent and the tumblr user:

I'm really new here so forgive me if I've broken any rules already.
