What is this lamp? I've seen the same lamp in old-style films and building ineriors across several countries.

Thanks.

The banker's lamp is a style of electric desk or table lamp often characterized by a brass stand, green glass lamp shade, and pull-chain switch. ... These types of lamp are frequently used in libraries throughout the United States, which have made the lamp popular through their presence in films and TV series.

Um.

Ah, I knew it would have a special name. Thank you
