I have had the Memo Book you see below and the colorful boxes below that since I was in my early teens. They were made by a company named Counterpoint San Francisco. I'm not sure of the exact year/years - late 60's, early 70's? I was then and still am a HUGE fan of the colorful items they produced.
Did you ever have any of these stackable boxes? They all fit inside each other, and they made different shapes of sets. I have had the set packed away for years. The largest box has lots of wear, but the ones that were inside stayed nearly pristine. There were the flatter set, and the hexagonal set - not sure what others. The colors didn't all show up well in this photo. The boxes and their lids are different colors - chartreuse green with yellow lids, hot pink with orange lids, etc.
I scanned the bottom of a few to show you the labels. My memo book has the same label inside.
Last year, I saw this set of metal canisters at a thrift shop. As soon as I spotted them, I thought "Counterpoint!". Sure enough, when I examined them more closely, I found the label still on the bottom of two of them. They're not in perfect shape - but I couldn't pass them up! You can see they are the same green and blue as three of my boxes.
As with so many things - I am always looking for more colorful Counterpoint items!
