I think this one is from 92ish? I have seen some older ones with different tags, such as the ones I have posted below. This one is older, doesn't have the 92 mark and also has a unique tag.
Not saying it's not from earlier, but yeah. I've only seen actual sub pop ones on a FOTL tag; not a vestibule, but i've also never seen one of the tags posted below in the wild on the shirts, also. Just some feedback!

It does look real from the pics you posted...
