Nike t-shirt w/yellow mercury foot, thread, 1 sleeve- real?

I foundvthis Nike tee at a local thrift yesterday. It's is unusual because of the yellow - a yellow mercury flying foot like image on the front, 1 (one!) Sleeve edge is yellow, the thread is yellow and it has a yellow tag on the lower side.
But a image search doesn't turn up another example?!
Can anyone tell me about a?
Is it a bootleg?
Any thoughts would be appreciated!

It doesn't have an RN on a tag?

It has a printed-in tag instead of a tag tag, so it's of relatively recent manufacture. The tag says 100% cotton, made in Honduras (of American components?) . It's in English, so likely made for sale in an English-speaking country. It looks like some sort of team logo. Beyond that..dunno.

 

The RN is included in the text of the printed tag. It is #54323. According to the Federal Trade Commission's web site the manufacturer is not Nike.

So...maybe shady doings? or...probably shady doings. But if so, why leave the wrong RN number in full view inside?

 

Well that stinks
