Do any vintage Tri-logo proof cards exist?

[Kenner76]

Does anybody know if any Tri-logo proof cards have surfaced over the years? One would think that some would be out there somewhere or at least would have been made back in the day. If not, why not? Thanks!

None are known to still exsist that I'm aware of. Perhaps Stephane has more insight into what and why.
