This is my all time favorite Fantastic Four comic. I think that Kirby's art and Stan's story in this issue capture the essence of what made the FF such a success. Starts off with some machine Reed dreamed up destroying Johnny's tux for Reed and Sue's wedding. They then zip off to battle the Skrull on a far away planet, saving the earth in the process (of course). And, after all that, they still manage to get to back to earth in time for the wedding rehearsal. 'Nuff said!
Eventually, I will have all FF V1 comics scanned front and back on my website. What I have so far can be found here: https://dekventures.com/FantasticFour/fantastic-four-v-1-regular-issues
