Discover 2679 Variants for 429 Mangas from 13 countries

Twice a year (winter and summer), Melonbooks chain stores hold a “Manga Festival campaign” where for every 500 yen spent (~3$) you get 1 point. Rules changed a bit over the years but at the core it was always the same: spend and earn points.
At the end of the campaign which usually lasts 2 months, you can redeem your earned points with various gifts. Prizes are always manga-related goods like postcards, tapestries, canvases, folders, and cover variants.
This cover is the prize for the winter 2019 campaign. You could have had it with 12 points.
