RTP also published a promotional leaflet that will be handed out in Tel-Aviv. It's available

Besides this, in the last couple of days they published the artwork for the promotional CD, as well as some photos from the postcard shootings.
I think this last week has revealed RTP's strategy for Eurovision 2019, in a way. Ever since Conan won FdC 2019 they've been pretty silent when it comes to promotion, or anyhting really. Even their social media for Eurovision has been almost inactive. And now that we are 3 weeks away from the contest they reveal all of those things in 3 days in a row, even the postcard photos that they were obviously witholding since the postcard shoot a couple of weeks ago.
It seems like they might be saving their promotion efforts for the last couples of weeks before the rehearsals and for the actual Eurovision weeks themselves, in order to try and build some momentum just in time for the contest, kinda like Cyprus did last year. For that to work they'd need killer staging and a big effort in the press meet and greets in May, though.
Or maybe I'm just giving them way too much credit
