Schrödinger's Bach Guild Big Box sets--exist or not?

[XB-70 Valkyrie]

Just found out about these while searching for recordings (reissues) of organist and harpsichordist Anton Heiller. Some of these sets look interesting, but apparently are available only as MP3s. It seems they once must have been CD sets(?) The term "Big Box" would seem to imply the existence of an actual box with physical object or objects inside it. (a box full of air seems to serve no purpose.) Were these ever issued as CDs? If so, where can one obtain them? FLACs?

You can get both of them as mp3s from Amazon:
