I had a grand plan for today's pic, but without the real hat, or any stickers that are close to what I was looking for, this will have to do. Phoenix is showcasing her sombrero (or something like it)... so which country are sombreros associated with?
The last couple of pics were for the Seychelles (21st), Japan (22nd) and Sweden (23rd) - though as Pyrrhula noted, while Ericsson is a Swedish company the work in developing bluetooth was done in Holland.
