Would anyone here know if this an official release recording of Bill Evans?

Bill Evans  Very Early Volume 1 
Label E3 Records.

That label seems to be defunct, but since it was initiated by Bill Evans' son, Evan Evans, I will assume that the releases were legit unless there is contradictory information.

E3 Records was a legit label that released at least two CDs of Bill Evans’ early recordings.
