1899 Weymouth, NS (Nov 3) on #P3 2c postal card for use to Great Britain, to Munich, Germany, paying 2c UPU postcard rate, redirected to Pasing
The 2c GB card was only allowed to be used to GB until 1879, after which regulations were relaxed, the P4 2c UPU card was issued and this card was tolerated but seldom used to foreign countries. Still a scarce use, but not as rare as pre-1879.
