The first Seasons beta tester has surfaced on TheSims3.com, and they have a greeting card uploaded to their Sims 3 Studio.
The photo looks like those taken at Prom in Generations, but since this is Seasons were talking about…you catch my drift.
Perhaps we will be able to upload greeting cards specific to each season? Or maybe this is festival activity related. Thanks to Martys15 for sending out an email.
