Although the band has been touring the past few years as a "reunion," only two classic lineup members rejoined the band on a permanent basis, Slash and Duff McKagan. The other two members Izzy Stradlin and Steven Adler did not rejoin the band, but both of them are featured on the new billboard.
Under each of the member's cartoon head are a link to GNR.fm. The website says "Destruction is Coming" with the hashtag #AppetiteForDestruction. The namesake album celebrated its 30th anniversary in 2017 so it's possible the billboard it tied to a re-release or anniversary edition of the record.
Both Stradlin and Adler reportedly rehearsed with the band ahead of their 2016 reunion but ultimately did not rejoin for various reasons. Both have also appeared sporadically as special guests with Guns N' Roses; Stradlin having last done so in 2006 and Adler in 2016.
