It’s a “Made in U.S.A” box that has distributor information for US, CAN, Asia and Latin America only. Most unlimited boxes have distributor information for all countries listed. It’s a very rare variant… I think it was one that @thecharizardauthorty was missing from his collection, but maybe he’s added one since his last collection update.
You can read a little bit about it in my booster box identity article (I’m still working on a few sections in the post. There’s lots more information that will be added once I have some free time )
