I found all of these together (stashed inside a small wooden wagon) and since I believe one can never have too many color cubes, and because it's nice to keep things together, I decided to list as one big set. The combination also serves as a reminder, to me at least, that stacking-layering these, in addition to making surface patterns, opens a much expanded terrain of creative play and design possibilities--with my first couple of photos just a suggestion of that sort of direction. Anyway, I am newly enthralled with the excellence and beauty of these every time I spend a few minutes playing around with a bunch--and the old paint on these is just gorgeous. 

Blocks are @ 1 1/8" cubed. The 72 older ones are very easy to differentiate from the 16 less old, especially by the brightness of reds, though both sets share nice rich solid yellows, whites, and blues, that distinguish them as themselves an older set.
