I looked into this a bit and yes, all hail Mr. Oldbuck! To the extent that comic books continue to be primarily enjoyed/produced by Anglophones the world over, especially since 1990 with the globalization effects of the great equalizer -- movies! -- it would be difficult to overstate the importance of the 1841 version of Adventures of Mr. Oldbuck, i.e., the one published in London by Tilt and Bogue. It appears that experts now agree that the Tilt and Bogue 1842 version was the very first comic book in the English language ever and certainly the first published in Europe. Arguably, the 1841 version is more important than the Brother Jonathan Extra IX version published in 1842 in the United States (New York by Winston & Co.). That is because there is no dispute that the 1842 Brother Jonathan version used the actual printing plates from the Tilt and Bogue version. The Brother Jonathan version may be the first comic book actually published in the U.S., but technically it was just a reprint of the 1841 London version! When funds allow (haven't quite figured out yet how to adjust my hunt for keys), I want a Tilt/Bogue Oldbuck book.
Now if only CGC would slab this thing too.... just out of respect!
