To buy: What's important


The sales's catalogues inclosing all offered lots usually will be released in print and online three to four weeks before the auction.
The thorough and careful catalogue descriptions, not only defining the author/artist, extent, dimensions and reference literature but also detailing the book's and print's condition, deliver a sufficient overview of the object's quality to interested persons not being able to preview the items. We will be pleased to send English catalogue descriptions to foreign clients on demand.

Estimate price - Starting price
Each object has an estimate price which serves as an approximate value guideline. The auctioneer starts the bidding at around 2/3 of the estimate, unless there is a higher commission. The objects are auctioned in bidding advances of generally 5 to 10% and are knocked down if there is no higher bid after being called out three times.


The preview, which takes place a week before the auction, gives the possibility to view and critically examine the objects to be offered for auction.

Bidding in person

Bidding in person is definitely the most certain way to achieve a desired object. Except for enjoying the thrilling atmosphere of an auction sale the bidder is able to react immediately to possible counter-bids. All objects to be auctioned are presented for viewing before being called up for bidding.

Bidding in written form

Another way to become a purchaser is to send a written bid. An absentee bid form can be found in our catalogues or may be downloaded here.  The form has to include the lot number as well as short object's title so as to avoid misunderstandings. The bid, representing the maximum bid possible, will only played to an absolute maximum by Venator & Hanstein if this is deemed necessary to outbid another bid, allowing to purchase the object as favourable as possible. This means for example that an object may be knocked down for you at 350 € even if your maximum bid was placed at 500 €. - A buyer's premium of 23% will be added to the hammer price; this premium is subject to the statutory VAT (margin scheme).

Bidding via online catalogue
A convenient and safe alternative to written bidding is bidding through our online catalogues. A full-text search will quickly get you to the lots you are interested in. After a usual registration or login you can send your bids directly. You will receive a confirmation straight by e-mail.

Live Bidding
We enable our clients to participate as a live bidder in the current auction via the auction portal Lot-tissimo ( The registration and entire administration will be processed by the named platform. The surcharge of 3% (plus VAT) on the hammer price calculated for live bidding will be charged by Venator & Hanstein.

Bidding by telephone

A further method of participating as a buyer is bidding by telephone. As we only have a limited number of lines we trust for your understanding that we can offer this service exclusively for higher valued objects. - Please contact us in written form stating your telephone number to be getting reached at the time of the sale.

Pickup or Shipment

After a successful bid the auction goods can be personally collected during business hours once the invoice has been payed in full. Buyers from out of town can have their purchases sent to them by parcel service once the account has been settled.
