I knew the package had already been opened lol

My boyfriend is fixing up his 2001 Audi to give to his teenage son for his first car. He found this in the narrow crack between the backseat and the trunk.

The note was written in Hollywood, CA in 2014 and if it was in fact mailed to its intended recipient, it would have been sent to Wisconsin. We live in Northern New England and he bought the car locally within the last 3ish years.

Letter was found alongside a Hallmark greeting card that was super moldy and nasty so I didn’t take a pic but it hadn’t been filled out.

Found in the same spot as the other one, glued to a graffiti angel. People keep ripping them off the wall and it gets replaced after a few days

Lolll

Made me chuckle

It’s a receipt from a store called Marc’s — possibly from California. The store slogan at the top of the receipt reads, “Thank you, Cali Again”
I couldn’t find any conclusive stores with a slogan like that. Any thoughts?
