Those venetian blinds could be considered sort of a "period accessory". They were in vogue when I was kid in the 60's, back in the pre-A/C era. Even then I thought they looked sort of dorky. I associate them with accountants who wear short sleeved shirts, skinny ties and a pocket protectors. Today's solution to the problem of solar heat load is tinted windows.
But hey, that's just my opinion.
