Partner Bill DeLind confirmed the artwork was located in the lobby of their building. The piece did not have a price or artist name attached to it.

“This is intentional. We didn’t want to attract someone who was just looking at values,” DeLind told CBS 58. “Somebody either knew what they were doing or just got lucky.”
