The two emblems were drawn for Ace Combat-related content, featuring mascot characters from Ace Combat Infinity. The yellow emblem was done back in early 2016 and the pink one was drawn in late 2017. I wanted to reflect the designs of official emblems that were introduced in the game, and the text refers to game-related events that took place during the time of the emblem’s conception.
Both emblems take reference from an existing design, with the former using Sonic the Hedgehog’s iconic pose in Sonic Adventure and latter paying homage to Rosie the Riveter’s famous You Can Do It! poster.
