I agree with the descriptions from chele and sandy and peckish. Moda has a line of fabric (a couple of years old now) called Shirtings 1875-1900 designed by Terry Clothier Thompson. I have yardage of a couple of the prints....they are small theme prints on a light background. The one I bought the most of has a very small red and blue baseball design....hands holding a bat and also a ball on a cream background.
I've read that these prints were very popular as men's shirt fabrics during the late 1800's as engravers and fabric designers developed techniques to make these tiny prints look realistic. The sports themes were very popular in that period. There's a PDF from Moda with a little history and display of the fabrics in the Shirtings line. I have some of the bicycle print too and it looks very cool in small pieces. Here's a link to the PDF:
