First gay antiques dealer?

This trope came up in conversation recently. It goes back at least to Agatha Christie's Murder is Easy (1939). But was that the first? I haven't found any prior literature with this trope. Arguably homosexuality was "invented" in 1869, so it's unlikely the trope predates that. I have found a painting of a real gay antiques dealer, who is strongly visually coded as such, from 1926. "Roberto Montenegro’s iconic portrait of the antiques dealer Chucho Reyes (1926) features the limp wrist, the tilted chin, and the wry smile that signified a certain type of man." Anyone else have insight to share on this?
