Horsey graphic green & orange retailer fabric

There are 4 pieces in this listing. I decided not to separate them, it is a vintage print you won't see anywhere these days. I'm guessing at the age, it was in my mother's stash and is probably from the 70's or 80's.

The pieces are approx: 43x24, 43x88, almost 15x19 and 18x19.

This fabric may have been washed, or not, I can't tell. It feels like it is brand new and hasn't been washed, but the threads are a little frayed at the edges which could mean anything. It's crisp and firm to the hand, a tiny bit stiffer than some quilting cottons which could just be starch? Sizing? I didn't wash these pieces so that you could decide for yourself how to treat retailer it, test wash, etc.
