I finally got my book!

I found it at Pearl art store. It was actually a bit pricer than I expected, but it's not the single volume - it's a soft bound collection of several of Preston Blair's books. At $30 it was still a steal.

So since I actually have my book now, I went back to the beginning and did some copies of drawings in the intro pages. The puppy didn't come out quite right- I made him blockier and less goofy than the original - but I think the scruffy dog is pretty close.
