Vintage Klompe Air Mail Floral Stationary Set made in Holland

Vintage Klompe Air Mail Floral Stationary Set. Made in Holland. This set says 10 printed sheets of stationery and 10 blank, the packet is closed with some old tape and I didn’t want to try and open it. I can for sure see 8 Envelopes and I am not sure how much paper is in there.
