"A Rally", painted by Sir John Lavery in 1885.

This superb watercolor titled "A Rally", by Sir John Lavery, offers a remarkable representation of the emergent lawn tennis and evolving social conventions of the late Victorian era.
Created in Cartbank near Paisley, where Sir John Lavery had a dedicated court for this activity, this work features young members of local bourgeois families.
Lawn tennis was still a relatively new sport at the time, with rules distinct from earlier versions of tennis originally established by the Leamington Tennis Club.
Lavery aligned with the Baudelairean ideal of modern life, which advocated refined social exchanges. Lawn tennis, with its ritualized interactions, provided an ideal setting for this.

This painting, currently on display at the Glasgow Art Gallery and Museum, charmingly captures the elegance of that era.
