Patreon advertisements in the card art?

Several of the cards in Cover Girls V have links to the author’s Patreon overlaying the artwork. I wouldn’t mind seeing it in the description section, or even one dedicated card that is just “Check out my Patreon!” but it really hurts the aesthetics of the art to have boxes overlaying the pictures and it makes me want to skip the series.

None of the preview cards had these orange boxes so it seems a little deceptive. Are artists allowed to do this sort of advertising in their sets?

If the markings are small and unobtrusive, yes we allow it for veteran creators. This is determined on a case by case basis.- Joe @ NeonMob
