My memory may be playing tricks on me, but I believe Drewseph offered both white and black versions of the DRD on Berdardpuzzles, the same way he did with his Master Skewb. I seem to recall asking myself whether my preference for black puzzles was strong enough to justify the extra waiting time, as white puzzles were usually given priority in being shipped out first
Also, the white version of his puzzles were usually offered at a higher price than the black version, due to longer curing times of the white resin (as Drewseph mentioned here
). I believe most people went with the black version (at least this was the case according to Konrad's statsitics for the Master Skewb
), so if the DRD being offered here was made by Drewseph, it might be one of the few white ones in existence.
