An upcoming New York City auction features the belongings of movie cowboy Roy Rogers — including the preserved remains of his famous horse, Trigger.

Christie's in Manhattan held a preview Friday for next week's auction. The items are from the now-closed Roy Rogers and Dale Evans Museum in Branson, Mo.

Rogers had his faithful companion preserved with taxidermy in 1965. The presale estimate for the dead horse is $100,000 to $200,000.

The auction also will offer another kind of horsepower — Rogers' 1964 Bonneville convertible, adorned with collectible silver dollars. It's estimated at $100,000 to $150,000. Also, h and-drawn music for the theme song "Happy Trails" has a presale estimate of $300 to $500.
