Early 1900’s Circus Advertisement Poster

I was bequeathed this antique early 1900’s circus poster from my grandmother who had stored it in an antique cabinet with several others until her passing. I was gifted one from my uncles after my mothers passing and they quoted the value at approximately $1500. This gem is approximately 54 x 39 inches. It featured a woman holding cotton candy while riding a horse in a merry go round. It appears to have had a top half at one point in time? It has been folded and kept indoors for around 90 years! The paper is very brittle, with creases and holes at several of the folds and corners.
