I know I just posted an update yesterday, but just this morning I received this package and I really wanted to show you. Here's a video:


It looks gorgeous!

Leather cover preview + ALL signatures signed!

Sandy has finished signing the re-sent vellum sheets, and they are on their way back to the printers!

It will NOT slow down our schedule as I briefly feared. This is because the normal procedure is to ship the signed vellum sheets back to the printer's US office, who then forwards it with their normal freight forwarding to their China office. This costs less, but takes longer. We are shipping the sheets directly to the Chinese printers at our extra cost so as not to create any more delays. So, the initial name misspelling won't affect our schedule after all.

The truth is, any design, development, printing or manufacturing process is fraught with little issues like this, and most of them happen behind the scenes. If they were all shared, you'd feel well informed, but I'm not sure if you'd feel better about everything!

In any case, I told you about THIS one little story. Hope it was interesting for you.

Also, here is a cover (only) sample of the stamped leather for the collector's edition:




Digital Print Proof Pics + Vellum Insert

Pics of digital print!

I can't get enough of seeing the physical book. I know you have the digital download, but it's different when it's real. This is just a proofing copy, it is not bound, nor does it have the proper cover, but the pages themselves are accurate colors, order, finish, etc. 











Vellum for Signing

The below page is ONLY in the collectors edition, it is a vellum, translucent material, and is the page where Sandy will sign the books!  Yes, he's REALLY signing them as promised - no "stamps" - with a sharpie, no less. 

We did actually discover that my name is misspelled on the vellum sheet AFTER he'd signed about 200 copies. What made this more frustrating is that back in November we'd caught this typo and had sent a corrected file (and the printer acknowledged receipt of the revised file). But, then, when we received the pages for signing, saw they had used the older version!  Stuff like this happens all the time in the game development and printing/manufacturing process - a combination of human error and bad luck. I don't believe this will greatly impact our timeline, but I'm not certain yet. If it does, I'll update you. 


This is what the next page looks like (vellum page for signing is on the left). The idea is that since you don't have the cover of the book with this Cthulhu (since it's leather), then you still have this image of Cthulhu inside to look at:

I know you are slathering for more updates!  I've been asking the printers for pics, and I finally got some to show you!




Also, likely of interest to most of you, below is the file for the COLLECTOR'S EDITION embossing on the leather! 


Once I have a picture of the physically embossed leather cover I'll send it out too!


In other news, I've been relatively silent regarding the starter adventure download. It is in final editing now, and should be sent out in a few weeks!
