This exceptional 1911 transatlantic postcard represents a premier rarity in early 20th-century U.S. vending and affixing machine postal history. The card features an informative printed view caption for "Herald Square, showing the 'Great White Way' and Herald Building," published by noted New York postcard manufacturer A. C. Bosselman & Co. The card was dispatched with warm family correspondence from Arthur to his mother, Mrs. Sherman, at 18 Northbrook Road in Nichols Town, Southampton, England.

What elevates this postcard to exhibition caliber is the solo franking: a 2-cent carmine Washington issue with Schermack Type III private perforations (Scott #384). Affixed at a distinctive jaunty diagonal in the upper right corner, the coil stamp features wide, well-balanced margins and the unmistakable, sharp six-hole vertical slot control perforations characteristic of the Schermack Mailing Machine Company system. It is neatly tied by a New York, N.Y. Station C wavy-line machine cancellation dated September 22, 1911.

While 2-cent Schermack Type III coils were widely employed for domestic first-class commercial business letters, solo usages to pay the 2-cent Universal Postal Union (UPU) foreign postcard rate are exceedingly scarce. The card shows only minor, honest corner wear consistent with transatlantic transit, while the stamp itself is crisp, brightly colored, and completely free of creases or tears. It stands as a choice, highly collectible showpiece for specialists in early private coils, vending machine mail, and destination postal history.
