He still prints Miami made box dates IIRC. Its when he opened the new factory in esteli (spring 2010?) (red labeles, moved la ricky and cabis there, EL Ts and everything else under the sun) that he quit printing box codes on all Esteli products. The "formely known as Pete Johnson" logo was then added at to products like the J21 and & 7th Resevera (<--when they came out) So a 2010 box or older of J21s should still have the regular J21 logo on it.
