For dads who appreciate modern art, try this unique card by Iowa's Moglea. This hand-painted card has foil-stamped text that reads "so grateful for you dad" and is paired with an envelope.
Measures 4.25" wide x 5.5" tall, blank inside. Painted on gray pulpboard cardstock with swathes of white and mustard paint so the background pattern will be in different shapes than pictured. Comes in a clear sleeve.
