Is it possible to still get physical copies?
As the designer I don't know that I'm the right person to speak on this, but I'm not sure there's a big difference between the original and the POD. Original print has a slightly glossier texture to its cover, but I don't think I could tell them apart in a lineup.
If you're looking specifically for an original, the copies at Exalted Funeral and Floating Chair are out of stock, but third party sellers may have them.
