Barcelona

One point per season, placed by its year: the number is the shirts in the archive, the price the cheapest listing you can buy right now, rounded to the euro — the exact figure is in the point’s tooltip, and “—” means the season is archive only. Seasons that share a year are stacked, a year without a point has no shirt indexed, so a gap on the axis is a real gap. Below 900 px the points are grouped by decade instead of one long swipe.
