I remember being excited to finally have some new Mickey content featuring the voice of the late Wayne Allwine as Mickey. The show was "Mickey Mouse Works" and featured a quaint CGI factory introduction showcasing the "animation process" from drawings to ink and paint.
Unfortunately the show aired on Saturday mornings at a very unreasonable hour. It's like they didn't want anyone to watch it!
Setting up a VHS player to record episodes onto blank tapes bought from the dollar store was the solution. I still have some of those tapes!
I don't remember much advertising and recently had a hard time finding any promotional material or quality images.
