If you're looking for some interesting official AB6IX merchandise you should definitely think about this poster. It comes from their album 6ixense. 6ixense is the first studio album of the group and was released on October 7, 2019 under Brand New Music. It featured 11 songs including the lead single titled Blind for Love. All of them are a wonderful pieces of music.
The poster was included as a bonus to all pre-orders of version Sense of 6ixense. It measures 841 x 594 mm and features all 5 members of the KPop group (including Youngmin for who this release was the last before he left AB6IX in June of 2020).
A different poster was included as a benefit if one purchased the other, 6ix version of the studio album. It features a photo from a different photoshoot, while the one you're looking at comes from the same photoshoot the picture on the album's cover comes from.
You can get this original poster for a very affordable price from Amazon.
