I really don't know that much about Blackjack. I tried it a few times, but I prefer a game where there's more choices, and the ramifications of said choices are much more tangible. I do know that a face and an ace is an opening hand where you just win. Wanted to draw Frankie slamming down some cards in a dramatic, victorious fashion. I was thinking of it being maybe something like koi koi or mahjong, but I decided against it in favor of more recognizable iconography.
