Archie,
I am insured with Collectibles Insurance Agency & below is the information on Shows from my policy.
Andy - Las Vegas

>>>$40,000 SHOW AND TRAVEL COVERAGE in the US and Canada, including unattended vehicle, checked baggage, vacant hotel room and show theft.

You are covered from the time you leave until you return with very few exclusions. If a show or travel loss is over $100 in replacement value, we pay the loss up to this coverage limit without a deductible.<<<
