Reference books?

I'm currently trying to reproduce Sailor Jerry designs and really dig deep into the style and get myself to a reasonable level. I'm trying to learn and I'm really eager but I'm finding Google images to be underwhelming. Does anybody have any *affordable* book recommendations or (if it's within the rules of the sub) any suggestions of where I could find pdfs of books?

​

It'd be really cool and thank you to anybody in advance for helping.

I hope this doesn't get taken down because I used Sharpies instead of paint for the pig and rooster I did, I appreciate any advice.
