You could upload the Starz Originals promo of The Chair, which was being shown at the time (September 2014). The show premiered on Saturday, September 6th, 2014.
Were they still using the old 2005-2013 Encore logo, as a secondary logo, during December 2013, before it was quickly retired? 🤔 Good thing I have a PDF file of the Encore schedule from December 2013. It begins at 11/25/2013 and cuts off at 1/5/2014. Fun fact: After 12/29/2013, Encore officially discontinued the Big Mini Series Showcase block. Here’s an interesting question for you: Can you prove the earliest known use of Encore using their 2013-2016 logo, on some select promos (at least shortly before December 2nd, 2013)?
