My father wrote a message on the wall every time he changed the wallpaper "My wife forced me to change the wallpaper ..AGAIN!".... with month and year, so he had a proof when my mother wanted to change two years later again....

I used to work at a hotel,that was,built in the early 1900s when,renovating the hotel we found writings on the walls from 1914.

It's common practice for carpenters to put a section of the newspaper inside a wall before installing the drywall so that some future carpenter can find it.

Not in the walls but on the back of the original furnace (circa 1947) when I replaced it in 1994....Mickey Mouse cartoon pasted to it (circa 1950).....

When a contractor was re-plumbing my bathroom in 2014 I stashed a plastic bag in the wall with newspapers from 2010, 2012, and 2016 celebrating the SF Giants' World Series wins. I put silica grains in the bags to keep them from getting moldy and a note describing the changes I've seen during my residency since 1982. I have found newspapers in the building's walls from 1927 and 1964 and hope my 'time capsules' are likewise discovered in some distant era.

As someone who's done many renovations, this article is great! I've never left anything like this for the next tenants but I'm going to now.

My ex-husband was practicing drawing his pistol in the bathroom and shot a hole through the bathroom mirror into the wall. Before replacing the mirror, I wrote," this is what happens when dumbasses play with guns."

I lived in a 1930s apartment before 2004 and the mirror was set in a recess in the wall and fixed with a rubber washer all around, so one day, out of curiosity, I took it out - someone had written "The truth is out there" in 3 inch letters...

Very jealous of the people who found nice surprises. A couple of days ago my wife and I tore down the insulation in our basement and found two empty bottles of blackberry brandy and a can of contraceptive spray, which I didn't even know existed.

Remodeled a closet and found a 1963 Falls City beer can sitting in the wall--had the ROUND hole on the top. Some workman's lunch beverage.

When my husband rebuilt our front porch in 2005, I left a time capsule underneath before he replaced the floor. In a Mason jar, I left the A section of the local newspaper from 5/05/05, a picture of who lived there, and a note that ended with "Did you guys ever get that stadium thing figured out?" figuring there would be at least one stadium thing going on whenever it's found. Thanks for reminding me!

Hidden in a wall of a room we built, we left a small bible with a picture of our family for someone to find. We also said a prayer for our family, and any future family, that makes memories there.

I've left messages and drawings on my teenage bedroom walls in our family house some 30 years ago. The house has been sold 2 years ago and I wonder if they have been discovered...

who would hate this - every note you teachers ever sent home - god bless my mum

Our bathroom contractor found an edition of the Sacramento Bee newspaper from 1954, my birth year. They tossed it days before even telling me. I was so disappointed with not being able to read through it.

I love this!

The new bathroom does NOT look amazing. It just looks new. It is all white, industrial-looking and will quickly start to look not so new due to all the white. To each their own (but then let's not make blanket statements like that).
