Hysteria Question

Hey everyone! I have several Hysteria sets & packs installed on my computer with no other info other than the event number (Hysteria 16, Hysteria 24 ETC) When i searched for the covers on Borosix there is 2 of almost every event normally held a week or 2 after the first. So my question is how do i find which is the correct event that the sets are from when it could be either?

Anybody have a clue?

i think normally the one where the title is flat on the flyer not stretched or at an angle,used to have a few of em years back,like 11 13 15 16 majority of em was in the south aswell,some london n north tho
