LOUISVILLE, Ky. (WDRB) -- Iroquois Park has been transformed into the site of Louisville's newest must-see Halloween attraction as part of the Jack O'Lantern Spectacular that opens tonight.

It took an artist about 10 hours to not paint but carve Albert Einstein's face on one of the 5,000 unique creations.

For the past three weeks more than 30 local artists have been drawing, carving and chiseling thousands of pumpkins into works of art.

Mike Cadieux, one of the Jack O' Lantern Spectacular organizers, says it's a labor-intensive project.

"From picking the pumpkin up to choosing the image to drawing it to carving it, I think 10 hours would be a good average," Cardieux said. 

The theme of this year's show is "Around the World."

A half-mile trail takes leads through Italy to the tower of London -- even to Kentucky. Music and strategically placed props enhance the brightly lit pumpkins.

"We're going to scrape them out so they glow brighter so everything looks nice and crisp and clean and orange," said Matty Scianname, another event organizer. 

You won't find candlelight though -- tiny light bulbs illuminate each Jack O' Lantern.

Cardieux says they use Christmas wire and custom sockets in every pumpkin.

The show runs through Nov. 2, but Cardieux says the pumpkin art is ever-changing.

Since pumpkins only last for about a week before going bad, artists must work around the clock on fresh replacements. 

"Depending on weather, humidity down here, the rain, they can rot in two day," Cardieux said. 

Proceeds from the show benefit the Louisville Metro Parks Foundation and Kosair Charities.

Of course the time to get see the show is at night. The trail is open from 7 p.m. until midnight Monday through Thursday, and from 7 p.m. until 1 a.m. on Friday and Saturday nights.
