Which auction house would you suggest?

[Codymilo]

Hello,
I have an American Retro Ferrari pedal car that has over 30 signatures of historic drivers from the 50’s, 60’s and 70’s. I collected all of them over the past 20 years up at Monterey Historics Laguna Seca CA. Shelby, Hill, Gurney, Moss, John Fitch, Unser etc etc. The signatures are authenticated by JSA. I’m looking for a venue to sell the car. Barrett Jackson, Mecum, Goldin, as well as several auction hiuses in Europe want to represent it. I’m not sure of putting it in an Automobilia auction as I don’t feel this is just a pedal car but something that should be displayed in a collectors garage or house. I feel it needs more exposure. Does anyone have any suggestions that might help on where this might get that exposure?
Thanks for the help!
