This is the "12 Classic Poses" red Sonic tee.
It is seen here, at a Sears store in the boys/teens area. It lives up to the name with 12 poses...but you can also notice that quite a few of them are the Japanese poses that are from the era, but were never really used much outside of Japan. You can see 'looking out', 'running with chin up', 'balancing' and more are in that slightly different style from an early artist.
Despite being all-classic all the time, these "new to you" poses keep the shirt looking fresh while still being classic. This was probably around 8.99 or so, and likely to be from 2017 or very early 2018. Remember, Sears is closing up many stores throughout 2018, removing the ability for fans to buy tees which were exclusive to Sears.

Here comes an attempt to be trendy with this "Hash Tag Tee".
This is by Bio World (good to see them back in the game in early 2018) as you can see with their blue tag there. This red tee is only for little kids sizes, which is too bad because it uses some neo classic Tails art. They're attempting one of those Twitter hash-tags with the slogan "Bro Bump!" Where the normal running Sonic is tilted to look like he's doing a fist bump with the Tails art. It's a tad "how do you do, fellow kids" but because it's only for small children no one is likely to make fun of it from that angle. This is seen here in a Sears store, and was likely 6.99 when it was on shelves.

Old Navy stores are known for pretty standard looking stuff, and this classic style light blue tee is no exception. It's just a plain pale tee with a simple side-view running Sonic in a simple circle. It has the classic logo at the bottom, and some of that weathering / faux wear to the paint to make it look old before its time.
There's nothing outstanding about the tee good or bad. It's found in the boys/teens section in 2018...and is an all right one to get, if you didn't have anything just like it already. It does not have a 'maker tag' of paper anywhere, and the print tag in the collar doesn't really name a company other than the Sega copyrights.

Target gets a new Sonic tee in 2019.
Your monitor does not decieve you in this case, it is actually a light/vague pinkish color (for some reason) It uses the very old/classic Japanese running/profile Sonic art for its design. This is the version where he has no eye-shine dot (as most of the black part is hidden) but it makes it look kind of flat. They have decided to pattern Sonic with various sizes of shaded gold rings everywhere he is blue.
It's a bit of an odd design element, but it hasn't been done on anything else before really. At the bottom you can see his name spelled out in a simple black letter Japanese font. They really seem to be looking for 'the Japanese effect' by using the lettering and also choosing a very old / distinguishable art. It's a little unusual for the boys section at somewhere as mainstream as Target, though.
