I recently had a box of Montecristo Petite Edmundo brought back for me from the island that was purchased at the LCDH in Varadero at the plaza. The box looks like any other box of Petite Edmundos I've ever owned except that it has a yellow Montecristo Petite Edmundo sticker on the outside rightmost side of the box and a yellow Montecristo insert; both similar to that of the Double Edmundo presentation. The box that I have from April 2017 does not have this extra "flair". The barcode checks out on the Habanos website and they look/smell remarkable, so I don't doubt their authenticity just yet but I thought given the volume of Petite Edmundos bought/sold/consumed within this community someone could shine some light on this subject. I will update with photos when I get home.
Thanks!
Edit: Added location of purchase.
