I still think the '80s were just yesterday.
This is probably mid-70s onwards, after Said took over.
There was such a huge change between what was going on before that and the"early period proper", I suppose, which is Harris period.
But Boffo stayed on until '77, and Dobson stayed for a short while too, and Dobson did have artistic input - Tiger is his design, even though he was employed as manager, so there is an "inbetweeny early period", of early - mid-'70s while there were still Boffo and Dobson having an influence.
I really think when folk refer to "Early Mdina" they are referring to Harris period. Things changed too much afterwards to consider them as being in line with the same sorts of work.
I did collect some mid-70s stuff, but I'm very fussy about which sort. I like the Boffo/ Dobson influence still having some sway. I'm not really interested in anything later than that at all.
