What era is this bright floral beauty from?

I bought this clutch at an estate sale, I was drawn to it's beautiful colors and pristine condition. A bright floral with gold satin lining and a hidden brass clasp.

No tears, stains... nada. It doesn't appear to have ever been used! It's for this reason, I have not used this purse once, keeping it in it's unbelievably great vintage condition for a collector.

I know it's a Lennox bag but at this time I'm puzzled as to the era it is from and have not been able to pull up much information online about Lennox bags.
