I bought all 4 available covers on 20/8/79 (day of release) and mine are all blue so that’s not true.

how else can we know if they are first pressings or not?

help me please. I'm new and learning still. I have a Led Zeppelin in though the out door Sleeve "A" vinyl record . I need to know if it is first pressing, or what I actually have? matrix reads ST-SS-794345-L STRAWBERRY (PR) (SP) 0-5SM2-

I have looked all over discogs.com ebay, popsike and I don't understand how to know if its a first pressing or not and what pressing it even is. Please send me some knowledge.  Thanks amanda
