Here's 8 different flags for some of the Warlords of the Three Kingdoms era. It includes, Cao Cao, Sun Family, Liu Bei, Gongsun Zan, Lu Bu, Dong Zhuo, Yuan Shao, Tao Qian. I plan on releasing more flags, but I'm out of time for new projects and will probably have more time in September.
The image should be standard paper size for a printer 8.5x11, and the flags are scaled for 15mm armies. Let me know if there's any issues that I can fix.
