kit–cat

1 usually capitalized K&C or both Ks :  a member of an early 18th century London club of Whig politicians and men of letters

2 [probably so called from the portraits hung in a dining room of the Kit-cat club whose low ceiling made the smaller size necessary] :  a portrait of less than half length but including the hands some thirty major portraits hanging on the walls, besides kit-cats, heads, sketches … and all the lesser oddities of a collection many years in the making — Clemence Dane
