This is a drawing of a person interacting with a ghostly figure. There is a spectral figure with a halo, called "Saint Serge," alongside another figure gesturing dramatically towards it. The ghostly figure is elongated and ethereal, with flowing drapery resembling a robe. The second figure appears to be dressed in a theatrical or period costume, posed in a way that suggests communication with the spectral figure. The style shows strong contrasts of light and shadow, typical of caricatures, emphasizing exaggerated features and expressions. The background is minimally detailed, focusing attention on the interaction between the two figures.
