Martin,
Thank you! for finding and contributing the very handsome publications by "banca popolare di sondrio," as these truly portray a special time and place. In particular, I locked in on an image of a TIGRA team rider - just behind Kübler + Koblet in one photograph. This because I own a Tigra racer from that period (early-mid 60s).
