Great Plaza Two-fer listed on eBay in airtight case...with blue capsule included in the deal. The Plaza Two-fer was the first and very best chase strike issued and remains one of the most beautifully designed chase strikes, however, it came in a yellow capsule, not a blue capsule. Only two chase strikes came in yellow, the Plaza and O'sheas Donkey and Elephant. Both highly collectible, but even more so in a yellow capsule.
