Best of 25 Years Stamps As part of Stampin' Up!'s 25-year anniversary celebration, they're bringing back some of your favorite stamp images from the last quarter century and combining them into 12 sets, which will release-one set per month-during 2013. Even better, along with some great classic images, each "Best of" set will also include a never-before-seen image!      Check back here every month to view a flyer for a new Best of stamp set! Some things to remember:  All Best of stamp sets will include 3-5 images, including a never-before seen image, and will be priced at $14.95. While they are releasing just one Best of stamp set per month (with a new theme each month), all of the Best of sets will be available until March 31, 2014. A new flyer will be released every month for each new Best of set. All Best of stamp sets are available in Clear-Mount only. As a special incentive to collect the Best of stamps, they're also including a collector's card and 25-year proof of purchase sticker with every Best of set. Collect six stickers, and send it in to redeem a FREE set of your choice valued up to $14.95! Free sets must be redeemed no later than April 30, 2014.
