The Spanish 7" single for Sat In Your Lap has the same artwork front to back as the UK release. However, the quality between the two are miles apart. The Spanish one looks like it was copied using a poor man's version of a colour photocopier. The song title is also listed on the front in Spanish.
The sleeve itself is paper, but it has a sort of waxy feel to it. At least it does to me, and it feels gross.
The single has a large centre hole and features both English/Spanish titles on both sides.
