Firstly, have you all seen the new USPS website for stamp discussion and release dates? It's www.uspsstamps.com and it's quite lovely. I'm fond of the time line feature where you can view exact release dates for stamps. You can also buy stamps directly from the site.
Here are the most recent three releases; two secular holiday issues and a new commemorative for the Medal of Honor. I really do like the holiday wreath and will be happy to use it on my overseas mail for the Winter season. The gingerbread houses are cute enough, and I can see a lot of potential for them in illustrated mailing. As of today, all of these stamps are available. If you can't find them at your local post office, then we suggest ordering them online from www.uspsstamps.com. You'll get the stamps you want and the shipping fee is minimal.
