No.
Had raised my voice that there needs to be some branding that could be shared at openclipart. If we think a side project of the inkscape developer team (Bryce) could announce inkscape related material -at openclipart- we need some images of the branding going well with the cc0 license...
and looking at the vectors team it was my intention that things are done only if you do them. Since noone else is interested in openclipart, that's why I "took the majority". It's non official as per se, but there is no approval system what should be called "official" either.
Honestly my 0.91 about screen image had the inkscape logo which is a no-go at ocal. (At the time there was no inkscape gallery and we needed to share the svg to the public... with a very few options this was the esiest to upload to.)
And recently the key-shortcut layout had been presented with the official inkscape logo -they both need to be hidden from the public of the pd issue. Thus we NEED something that can be used instead. Cheat sheets are more than welcome. Why shouldn't we have them just because we can't have a public domain branding double?
Hence this image in the original post came to life. Way too simple for trademark claims I guess, but the essence is there. (In that matter it's even more mature than the official logo. Have you seen affinity designer's logo? Or ai's? Now those are something sleek...)
Off topic:
re:inkscape vectors team: Haven't been following much the issues on gitlab of the team -since getting the e-mail notifications and there has beeen plenty of them. Either the information presented doesn't worth the mail notification or the conversation rather be presented in a forum instead... {[(Why not here?)]}
Have to catch up on that stream weblog series (?) but quite surprised it got the "official" tag whereas neither this forum, or Brynn's, or the facebook group got any official approval.
