From Danish media retailer iMusic: https://imusic.co/exposure/16963/lukas-graham-4-the-pink-album-  . Both the CD and vinyl are first editions with a bonus track. No info if the copies are signed by only Lukas or the whole band, but I would suppose only Lukas.

Internationally, he/the band is probably best known for his/their 2014 and 2015 tracks "Mama Said" and "7 Years". In 2022 they have had a domestic hit with "Wish You Were Here" with US singer Khalid.

Imusic ships pretty much worldwide, and I recall that their international postage rates are fair. I live in Denmark myself, so I can't check. I also believe that payment isn't taken until dispatch, at least it's like that for domestic orders.
