The Chateau is a castle on the shore of Lake Geneva, and is now used for events and exhibitions.  The sepia card was mailed in 1921 with stamp, postmarks, and a very long and readable message in French.  This is a nice historical artifact.  Grade: 1

We are indebted to Wikipedia for the essence of this:  The Royal Château de Blois is located in the Loir-et-Cher departement in France, in the center of the city of Blois.  The residence of several kings, it is also the place where Joan of Arc went in 1429 to be blessed by the Archbishop of Reims before departing with her army to drive the English from Orleans.  Built in the middle of the town that it effectively controlled, the chateau comprises several buildings constructed from the 13th to the 17th century around the main courtyard. It has 564 rooms and 75 staircases although only 23 were used frequently. There is a fireplace in each room. There are 100 bedrooms.  Too much information?  Mais, non.  The unused card is ornate but exceptionally flimsy, as if all the strength had been sucked out of it.  Grade: 1

Mailed in 1959, with two different stamps and Thun postmark.  Grade: 1

Not a typical Disney postcard, but an official one.  Made in 2012, mailed in 2013, with three stamps, postmark, and bilingual blue Priority label.  Unusual and a great addition to any Disney collection.  Grade: 1

This card was mailed from Japan in 1960, but from a U.S. military facility, so it has a U.S. 5-cent stamp and that military postmark.  Unfortunately that 5-cent stamp wasn’t enough, so there’s a “Postage Due 2 cents” mark in the address area.   Grade: 2

Unused, noticeably aging, clean old postcard.  Grade: 2

Unused Dexter Press card 58752-B, with 13 views identified on the back.  Grade: 1

Again, from Wikipedia, “Carisbrooke Castle is a historic motte-and-bailey castle located in the village of Carisbrooke, near Newport, Isle of Wight, England. Charles I was imprisoned at the castle in the months prior to his trial.”  It, or a predecessor, was built as early as 544 A.D. and something was opened in roughly 1100.  When our estimates must vary by centuries, you know it’s an old castle.  So too the unused card, though not quite as far back as that.  Grade: 2

Unused, aging card captioned in Spanish, English, and Russian.  Small tape along reverse upper edge.  Grade: 4

There’s no sign this card (1990s?) was postally used but it has a pre-printed stamp on the reverse, a long message but no address, and some tape at the reverse top.  Grade: 4

Mailed in 2014 with stamp and partial postmark.  Grade: 1
