此手繪地圖畫1883年《中俄科布多塔爾巴哈台界約》簽訂後之中俄西北新邊界，邊界以紅綫標明，左上褐色地域屬俄國，右下歸中國，俄國領土内亦以紅綫畫出1869年《科布多界約》所定舊界。地圖最左端為額爾齊斯河，最右端至阿爾泰山脈。俄國地域内部分河流及原屬清廷的卡倫據點均用中蒙雙語標名，然中國領土内僅標出約位於哈巴河域内的崇教寺（或爲藏傳佛寺）及寺前吉林河，並以虛綫繪寺廟出入綫路三條，此地圖之用處或與該寺廟相關。
請注意本拍賣品需要徵收進口關稅。進口關稅應為最終落槌價加買方傭金總額的一定比例。如果您指示佳士得將拍賣品運輸至一個美國境外位址，則您無需支付進口關稅。否則您需支付進口關稅全額。

Please note that this lot is subject to an import tariff. The amount of the import tariff due is a percentage of the final hammer price plus buyer's premium. The buyer should contact Post Sale Services prior to the sale to determine the estimated amount of the import tariff. If the buyer instructs Christie's to arrange shipping of the lot to a foreign address the buyer will not be required to pay the import tariff, but the shipment may be delayed while awaiting approval to export from the local government. If the buyer instructs Christie's to arrange shipping of the lot to a domestic address, if the buyer collects the property in person, or if the buyer arranges their own shipping (whether domestically or internationally), the buyer will be required to pay the import tariff. For the purpose of calculating sales tax, if applicable, the import tariff will be added to the final hammer price plus buyer's premium and sales tax will be collected as per The Buyer's Premium and Taxes section of the Conditions of Sale.
