Well gents, it's embarrassing that it took me this long to figure it out, but this year is the one hundredth anniversary of one of my favorite pieces of fiction ever, At The Earth's Core, the first of the Pellucidar stories!
One hundred years and it's still entertaining retro nerds like me! Ain't that just amazing? It's certainly one of the biggest inspirations I received for writing, and considering all of the different forms of media it has had to compete with is an astounding testament to its staying power! Okay, I missed the precise time of publishing, which was in April, but at least I got the year right. ;)
Party time ladies and gentlemen! Keep reading your beloved pulp and drink your Ovaltine! Whooo! :D
