Sbk - Flugspende Vignette 27. Anyone Have An Image Of This?

In the 2021 SBK book in the Flugspende Vignette section, the last listing is "1948 Mailand-Basel" with a description of "#27 - Volo speziale Milano-Basilea".
However, this one listing doesn't have an image to clue me in as to what I might be looking for (all the rest do).
Does anyone know and have an image or link that could show me what that vignette looks like?

Not a great image, but I believe this is it:



There is also a general expo label for IMABA 1948, but that comes in more than one color, and there is only a one-line entry in SBK, so that can't be it. This one also matches the wording.

Thank you very much!
I don't think I've ever come across one of these online, but I also wasn't looking for this specifically.
Now I know!
Cheers

Here is a green one on cover

It almost looks like I'm more likely to find one of these by looking for Italian stamps.

Hmmm, Is that the Italian equivalent and I'm actually looking for this one? No mention of Milano though. I might just contact SBK directly.

That's the expo label to which I was referring. I'm assuming that's just a general expo souvenir? The other label, above, at least has the right words showing in SBK's listing? Educated guesses, only. My Sanabria is a 1946 edition, so that's no help.

I went through Zumstein and didn't spot anything, but I'll look again. They sort this general type of material a bit differently than the categories used by SBK and I could have missed it. Easily.

Anybody have the Pellegrini airmail catalogue? Or the Schweizerischer Luftpost-Katalog?

You are absolutely right that the wording is an exact match. My only hesitancy is that I can't find any examples yet where this is used with Swiss stamps and it shows up in Italian postage albums. If this was a joint effort I would think it would also show up envelopes originating from Switzerland. It's not very common anyway, but I was left with questions from the examples I saw. Still very well could be what you suggested and I appreciate your feedback.

Interesting point. Hopefully someone comes along who has one of those catalogues. If it's in Pellegrini, we can probably rule it out as the SBK stamp.

Mystery solved - Schweizerischer Luftpost-Katalog 2018 shows it to be the ones that were originally suggested, according to a response in a Swiss stamp facebook group I am in. So it appears to be a joint country release.
