Looking for help in maybe identifying the origins of this arrow that I found painted on a cave wall near the Arkansas river in Arkansas. The paint is obviously not of modern origin. Arrow points to larger cave approx 50' upstream. Thanks in advance
Spray paint wasn't invented until the 1940's, and it even then wasn't a common thing for many years. Most painting like that would have been done with a paint brush, which can look different than what you are expecting.
