A US trademark search shows that "Just Say Rock" was first used in commerce in 1990, registered for trademark in 2004 and cancelled in 2012.

"Hello! My name is Inigo Montoya. You killed my father. Prepare to die!"

Lol, yeah I figured it's probably nothing. Just din't want to find out after the fact that is was some rare dot signifying something random. Hehe.

I don't think this is anything special, but I had to check first just in case, lol. Does anyone know if there's any significance to this tee? Its just a big black dot on a red 1980s Sportswear brand 50/50 tee.

Looking for the possible value of this tee I found yesterday. The front is a Harley eagle logo and the back shows it's from Phil Peterson's Harley in Miami. The tag is very faded, but you can still tell it is a Mayo Spruce tee. It is very good used condition with pilling and a few little faded ...

Ended up selling for $45

Post a picture of the tag as well for help in dating it!

Not sure as far as value, but "Keep Diggin" was first used in commerce in 1997, filed for trademark in 2001, and trademark expired in 2014. So I'd think it's most likely a post 2000 tee.

Looks like it's called "Butt Racer" and, unfortunately, it looks like you can still get them, too.

Here's an obscure one. "Hand Prints" brand on a ©1990 novelty tee.

Thanks, 5050! I was thinking they were older so that's good to know!

I came across two of this same Calvin Klein tee. I picked them up because I believe they are old based on their size, their shape, and by the material - it is very soft and super stretchy, thought not thin. I'm hoping maybe someone can help with the era on them as well as possible value. The tags ...

99% of the time - if it says "vintage" then it's not really vintage. That definitely goes for this one - not vintage. "Radio Days" was first used in 2002 and was abandoned in 2014 - http://tmsearch.uspto.gov/bin/showfield ... iyx4pt.2.4

I don't think that's a "1". I think it's a golf flag in a hole. Maybe that will help in searching?

Wow! Awesome find!

I'll keep an eye out during my hunting!

US Trademark website says T-America was first used in 1990. Filed for TM in 1991. TM canceled in 2003. So pretty much 90s.

I'd be wary of it because if you look at all of their clothing items they have listed, they are all gray Sneakers tri-blends and all size medium 38-40, with different random prints. Just my observation/thoughts. https://www.ebay.com/sch/Clothing-Shoes-Accessories/11450/m.html?item=382094314060&_ssn ...

Ended up selling for $60.

Thanks for the tip, XaronFisk! I went ahead and made that change so now you'll see the value when you hover over.

Hey Airmon! Thanks for the thoughts! I do know that prices can vary quite widely even on the same shirt. That's one of the reasons I put on every page that it's not a guaranteed value and that they should just use it as a guide amidst their research. That's also why I call the website a guide. It's ...

You could try Etsy and Poshmark.

Ok, yeah. If it was a 50/50 poly/cotton blend, I was gonna say it could be even earlier 90s because Artex Sportswear was first used in 1992, but my guestimation for yours would be mid 90s.

Possibly as early as 1986/87. I had a Paradise/Western Digital tee with this exact tag at https://www.etsy.com/listing/524409784/paradise-pc-graphics-card-t-shirt. Paradise Graphic Cards was purchase by Western Digital in 1986 and became Western Digital Imaging and the tee seemed to be promoting ...

This design of Artex tags did appear in the 90s. I have a 1996 Patriots tee with a similar tag here https://www.etsy.com/listing/523250896/new-england-patriots-1996-afc-champs-t and I have seen it on other 90s tees as well. Usually sports themed ones. I think yours may be a tiny bit earlier than my ...
