There are a couple of variations of the 487th Bomb Group patch, I have seen an early "transition" one that has a shield with a large aerial bomb/tree/cactus and above the shield there is a winged star with a side view of a B-17 and B-24 along with the two color "rope" of AF yellow/blue and a motto scroll below shield that says "Strength and Precision" then you have the colors variations of the G.F.M. there is one with a totally tannish brown background, then one with the bule sky/white clouds but the Devil is red with a lighter gray jacket/hat, then the one you posted with the devil in the Yellow form and yellow pitchfork and solid red flames.
All variations I have seen .
