This is a high-res scan of a reprint from what I can tell.

Sexhibition is made up of specific chapters picked from Suehirogari's japanese books Exhibition and Heartache, and the covers and color pages not included in Sexhibition have been included in this scan as a bonus (at the end.)

I agree with OP. This appears to be a higher quality compilation of the individual galleries.
This is far more convenient than the individual older galleries, and I appreciate the work that went into it.
You have saved me precious time.
