MOTM

This is a set of 4 books sold by Roland that deal with synthesis and
electronic music (from the late 70s).  They are really quite nice and cover
a lot of material.  I somehow ended up with 2 sets of these.  So, one set is
for sale.  Both sets are the same expect for book cover color.  I'm not sure
why they made them in different colors.

I'd like to get $31 plus $4 for shipping in the US.  I'll ship overseas, but
will need to re-price the shipping charge.

Here's a picture of the 4 books and the cover they fit into.
