“It’s a bona-fide piece of printed matter. It fooled me. This fella’s a regular Belasco. It’s a triumph. What thoroughness! What realism! Knew when to stop, too — didn’t cut the pages. But what do you want? What do you expect?”
Owl Eyes is amazed that the books in Gatsby’s Library are real and not just a facade. He says that Gatsby is just a “regular Belasco.” Belasco was a famous theatrical set designer for plays. His Sets here highly realistic and intricate, but they were truly just fake. The sets weren’t real life. Comparing Gatsby to Belasco, is saying that Gatsby’s life and wealth is a play, it is a facade.
