Absentee bids let you place your maximum bid on an item before the live auction begins. During the live show, we’ll continue bidding on your behalf up to your max bid — just like leaving a bid with a traditional auctioneer.
When you place an absentee bid, the system sets the current bid conservatively — just enough to keep you in the lead without revealing your full amount.
The current bid shown on each lot reflects all confirmed absentee bids and updates automatically as new bids come in.
When the live auction starts, bidding will begin at the current bid. The auctioneer will continue bidding on behalf of absentee bidders up to their max bids.
Because absentee bids can arrive seconds apart, the current bid you see may not always include bids still being processed. Refresh the page for the most up-to-date information.

Lot 228 - Grouping Of Six Vintage Souvenir Photo Postcards Depicting Demonstrated Phenomena At The Mystery Spot, Santa Cruz, California
Grouping of six vintage souvenir photo postcards documenting staged demonstrations at the Mystery Spot in Santa Cruz, California, a roadside attraction famous for its gravity-defying visual illusions and so-called unexplained phenomena. The postcards show visitors and guides performing classic demonstrations including apparent changes in height, objects appearing suspended or supported at impossible angles, and the “creeping ball” illusion. Each card bears printed captions identifying the Mystery Spot and describing the specific phenomenon being demonstrated. Black-and-white photographic images with period attire suggest early-to-mid 20th century production. All cards show age-appropriate wear, including corner softening, light creases, and surface wear.
