I received huge registered Star Trek cover from Canada! I am big fan of Star Trek and this is fantastic surprise from my friends Lars and Trevor. I received complete set of new Star Trek stamps on cover and inside as well. New Star Trek stamps are issued by Canada Post on 27.04.2017. and they are dedicated to Star Trek captains and you can see their biggest enemies in background. But they issued one Star Trek set on 05.05.2016. I received before old Star Trek set, but without lenticular souvenir sheet which shows the transporter room and the iconic episode “The City on the Edge of Forever.” I was lucky to receive this time this missing sheet, but it's hard to scan lenticular stamps properly, but i found this nice gif to show you how awesome is this.
Thank you very much Lars and Trevor for this beautiful surprise! Live long and prosper!
