There are 13 Byron's technique sheets. You get all that is shown in the pictures. Art Techniques #1 - 13.

These are new but have been in storage for a while. Some are newer and some might be vintage. Some might have holes in them for binders, have been folder for mail or have a bent corner.

I have lots of technique sheets. If you are looking for certain ones - ask and I will see if I have them.
