What are the little baby Blanton's bottles beside the regular Blanton's bottle?
Thanks for pointing them out. I'd never seen these 50mL Children of Blanton's either, google says that are available in random parts of the US but seem hard to find.
Baby Blantons.... Ask your local bottle shop to order them in for you. They retail for $5.99 to 10.99 depending on what state you're in. They have the wax sealed top, but no letter on the cork.
Because they're less than 2 oz, you can put a couple in a ziploc bag and carry them on the next time you fly.
