You can select Item Frames with specific items with the NBT selector:

/testfor @e[type=item_frame] {Item: {id: <Insert named ID here> }}

You can test for the rotation of items in an Item Frame with the NBT selector too:

/testfor @e[type=item_frame] {ItemRotation: <Number that fits into a byte; number of 45 degree rotations>}

Alternatively, it outputs redstone power via a comparator equal to the number of rotations, being 0 is upright.

You can test for the orientation of an Item Frame with the NBT selector (also):

/testfor @e[type=item_frame] {Facing: <Direction 0-3> }
