Representatives of Bally’s Corp. and Las Vegas’ Neon Museum are still assessing how they will rescue a stained-glass atrium canopy that arched over the Tropicana’s main casino for years.

But one other piece of Trop history — a blue neon sign over one of the entrances of the shuttered hotel-casino — was illuminated in a ceremonial flick of a switch Wednesday.

Neon Museum Executive Director Aaron Berger and Tropicana Vice President and General Manager Arik Knowles presided over a brief ceremony before several former Trop employees flipped a giant prop switch to brighten the patio in front of the museum store.

The sign was once mounted on the resort’s porte-cochere.
