Royal Seal?

According to a Yonhap report in the Korea Herald (April 1, 2015), a "Joseon royal seal [has] return[ed] home" to Korea:

A 15th-century royal seal of Korea has returned home from the Seattle Art Museum in the U.S., where it had been kept since 1963, Korea's Cultural Heritage Administration said Wednesday. The royal seal of Deokjong (1438-1457), a crown prince of the Joseon Dynasty, is believed to have been taken out of the country by U.S. military personnel during or after the Korean War.

Well, this may have been an April Fool's joke when first posted, but by April 3, no wolf in sheep's clothing is going to get up early enough in the morning to pull the wool over my eyes and get a jump on me! I can see plain as day with one eye behind my back - and the other squinting through a blindfold - that this creature is no seal - it's clearly a tortoise!

Some people might not immediately catch on, but a lad like me grew up among millions of these land turtles back home in the Ozarks, so if the voice of the turtle was ever heard in any land, it was heard in ours, not that I ever heard it. Our turtles are not the coo-coo kind . . .
