I was smiling during a good chunk of this book. It’s so wholesome and fun. Along with the Wedding Album special, this deluxe edition collects the issue before and three issues after the big event; this was during the triangle era, so issues are given chronological numbers for the year (1996).
Superman and Lois were broken up for a while before the wedding. In the issue before the wedding, Superman's powers are gone (he lost them during The Final Night), while Lois follows a story elsewhere and does some soul-searching. This issue ends with Lois and Clark reuniting and agreeing to finally marry. The Wedding Album where it happens is pretty great. It mostly features the lead-up, with lots of planning, parties, dress and suit shopping, apartment hunting, time with the in-laws, light superheroing, and more. I love that a bunch of past Superman artists drew this issue; the final fold-out page with past Superman creators drawn in attendance at the ceremony is a lovely touch (and I believe the priest is drawn to be Jerry Siegel, who died earlier that year). The three issues after the wedding show the wacky honeymoon in Hawaii, where Clark is kidnapped and Lois rescues him. Lois gets most of the action across these issues given Clark’s powerlessness.
Because the issues in this book were published during the triangle era, where four Superman titles fed into each other and constituted one long soap opera, it does feel like backstory is missing. The lead-up was longer than just that one issue before the wedding (hell, Clark proposed way back in 1990), and you're essentially dropped in the middle of a long-going story. Still, this is a fun snapshot of the era, one of the high points of 90s Superman comics.
Oh, and Clark gets a haircut right before the wedding, thus ditching the infamous mullet/ponytail!
Also, reading the backstory of how the wedding came about is interesting. It was meant to happen much earlier, after Clark revealed his identity to Lois back in 1991. But the Lois and Clark show began around that time, and because the show planned to end with Lois and Clark getting married, DC decided to postpone the wedding in the comics to coincide with the show (in the interim, DC did the massive Death of Superman/Funeral for a Friend/Reign/Return storyline). Then, when the wedding occurred earlier than intended on the show, DC had to rush to bring Lois back with Clark in the comics so they could get married at the same time as they did in the show. Even before the superhero movie era, comics were keen on synergizing with on-screen adaptations.
