My mother worked at Botica de Sta Cruz in the early 1960s. That was her first job. She had some Agfacolor snapshots. I think they had employee discounts 🙂. BSC was were Agfacolor CN 17 got developed and printed- and by what she told me, developing was in one of the rooms, set up not much differently from BW printing. Developing was done by hand, and was expensive. There's even one 120 Agfacolor negative which I printed which had the Hasselblad "double V" notches on the side. Never found such notches in any old negative other than this. This pic must have been shot by your lolo's Hassy??
The old Agfacolor CN17 negatives, despite being 40+ years old, were still printable. I tried printing them about 4 years ago, when I still had an active colour darkroom. The old strange looking yellow-masked negatives made prints with good colours which may looked better than what they got when these were first printed. Vintage Agfacolor prints I've seen are mostly purple now.
They also sold Leica- to this day, I'm still asking here why she never bought a Leica! 🙂

PS
Was your grandpa the one who married a German? Mrs Gutierrez, whom I met 10 years ago when she worked at the Goethe-Institut married someone from Botica de Sta Cruz, and was also into photography.
