I have made a few parody version of the well-known Uncle Sam propaganda poster. Uncle Sam originally wants you to join the U.S. Army but now he has something other thoughts for us. You can get these illustrations printed on posters, canvas, stickers, cards, coffee mugs, shirts and so on.
All of these examples you will find from my Redbubble store and some in Zazzle (under parody category).
Uncle Sam - I want you to wear a mask
Uncle Sam wants you to stay safe from the COVID-19
Uncle Sam - Bang Bang
He is pointing you with two fingers and bang bang!
Uncle Sam - I want you to fuck off
Now he is pissed off and giving a middle finger and wants you to fuck off.
