Billie Eilish Goldwing Poster - Happier Than Ever

Bought this for me but I accidentally bought two of them, i was gonna return it but m, never got the time and now it’s too late so I’m selling it on here. This is brand new, never been opened. The sizing is 24x36 I think. If u need tape or pins, hit me up, I got you. I don’t know about the shipping tho, I’m not sure how much this would weight, tell me if you got an clue
