[Funny, in a nice way, to see Ghent, the city I live mentioned here.]
Speaking of the Altar Piece by Van Eyck, soon (01-Feb to 30-Apr 2020) there's going to be "the largest Van Eyck exhibition ever"[1]:
In 2020, the Museum of Fine Arts (MSK) Ghent is organizing the largest Jan van Eyck exhibition ever. Only about twenty works of this Flemish master have been preserved worldwide. At least half of them travel to our museum. They are brought together with work from Van Eyck’s studio and copies of paintings that have since disappeared. But also with more than 100 masterpieces from the late Middle Ages. No less than 13 museum rooms are being redesigned for this.
