'tis lovely...
The group photo shows some of the variations in these early fish.
The fish vase is not signed Patrick, none of these early fish vases made in 68 or perhaps 69 seem to be, they tend to be quite small in size (5" or 6" tall). Most are not clear cased - which might be a slightly later variation. They are Michael Harris' early development of the design, the first couple were made at the RCA before he left for Malta. So they pre date MDG by a few years or so, not seen many fish vases from MDG at all, Sue has the one in the photo. I think that is Vincente Boffos style, this particular shape variation can be found in Mdina Fish vases in the mid 1970s too.
The last photo is the base of the blue vase, it was a real surprise when I first saw it.
