I never thought paper cut-out would generate such a discussion all these years later! I started annotating all the 2's with a school friend in about '93 or '94. Regarding my earlier observation of seeing paper cut-out on video in class in 1992, I remember thinking at the time that it was rarely, if ever, seen on air anymore. I would support the idea that it was withdrawn from regular use very early on, for whatever reason I'd love to know.
If it was, indeed, withdrawn at the end of 1991 then it's curious because it wasn't replaced with any new idents. Unless they didn't like it so much that they thought it was not fit for purpose (like Crystal Ball). If I recall correctly, I believe the idents and other pres were played off laser discs at the time, which naturally will have had only a certain amount of space. Could it be that they needed to make room for some Christmas pres and so they had to sacrifice an ident?
Another thing worthy of note is the original programme captions that incorporated the design of one of the idents in the lefthand margin. Pretty sure I've seen variants of every original ident, some even seem to have had more than one... all except Paper Cut Out.
I can certainly recall BBC2 North West using a static Glass ident well after 1993, probably for regional news junctions (remember 3.55pm?) or Thursday's 7.30 political/topical programme. Again, I would back you on this.
That certainly rings a bell. I do feel I saw it played out properly though and have Sunday morning in mind. Could be a false memory. We'll probably never know for sure.
