These Astra brand versions of Sanella cards are tough to find; wanted one for my type card collection for a while. I had one purchased a few years ago but it got 'lost' in the customs house in NY. This one was radio silent for a week in there but eventually showed up at my local post office and landed safely with me last week.
I hear that when you die you find all of the cards that have gotten lost in the mail, with all of the socks that went missing from the dryer.
