I saw a preview for the new direct to DVD Superman cartoon, The Death of Superman. In the promo, it says it is based on the “best selling graphic novel of all-time.”
That surprises me. Excusing the distinction between “graphic novel” and “trade paperback,” I would never have guessed The Death of Superman would have held that honor.
If you’d asked me that question, I would have answered Watchmen with some confidence. If not Watchmen, something like DKR or Kingdom Come.
Anyone have a list of the best selling TPB/GNs?
