Two Sealed Packs Containing Floral Aerogrammes From Series A and B With October 17, 1973 First Day Cancels

Two sealed packs each containing a complete set of the two issues of floral design Aerogrammes that were issued on October 17, 1973. These had a 15c face value and were intended for foreign usage. Each Aerogramme is cancelled with a first day of issue cancel. These used to be listed in Unitrade, but they no longer list postal stationery. My recollection is that each pack catalogued between $7-$10, so my estimate for the lot is $15.
