Starwars.com fills us in as to what to expect from Hallmark at Celebration V:
"Hallmark will continue its celebration of the 30th anniversary of The Empire Strikes Back with a Hallmark ornament two-pack to be sold exclusively at Star Wars Celebration V.
The ornaments depict Boba Fett with a Celebration V logo and Yoda with The Empire Strikes Back logo. The two-pack will be sold daily in limited quantities during Star Wars Celebration V and is limited to just 500 sets.
Hallmark will also be handing out sets of exclusive buttons. One set features some of this year's Star Wars Keepsake Ornaments while the others introduce a new Hallmark product line featuring Star Wars quotes. Different collectible buttons will be handed out on different days. A limited number of buttons with each design will be produced.
Additionally a Clone Wars Yoda Hallmark ornament will be available in the Celebration V store.
Other activities at the Hallmark booth include a sneak peek of the 2011 Keepsake Ornament line, a sneak peek at the new line of Star Wars gifts coming April 2011, a demonstration of webcam greetings, character appearances, periodic giveaways for kids and more."
