The bride and groom are chunky people, the little people figures made after the original people and before the current more modern figures. Chunky people were only made between 1991-1996 and were the reaction to safety concerns that the original little people were choking hazards. Although they were only made for a short time quite a few were produced.
The chunky bride and groom were the first wedding couple produced by Fisher Price. If you find an original (classic 1950's-1990) little people couple that resembles a bride and groom then you have found a unicorn, as special couples were produced only for Fisher Price staff as gifts when they married. I've never seen one in person but the couple is pictured on This Old Toy here.
I was inspired to share our little people bride and groom with you today because this evening I'm attending a wedding of a sweet young couple. They're so young that these toys were released while they were still babies. Ah youth!
Best wishes to the newlyweds!
