Some Short-Wave Listener QSL Cards

I haven’t received many, but I always like QSL cards from shortwave listeners. Someone out there is listening!

The top one is from recent contact. It arrives from Hungary via the W2 QSL bureau. Here is Tamas HA00001:

The middle one is from my youth.  in 1975 Nick in Moscow USSR heard my contact with OD5IO.   I didn’t remember the contact with Lebanon.  It turns out that the operator was K4NYY (who is now a silent key.  See https://www.qrz.com/db/K4NYY/?mlab=).

The bottom one pre-dates me by more than twenty years. It comes from Berlin in 1936. W5AIR was heard working EI7F. on 20 meter CW. Does anyone have any info on this SWL?
