Two more signs encountered today in Franklin Street Melbourne

Two more signs from today. I found another question too: how old does a sign have to be to qualify as a 'ghost sign'?

I saw a number of signs today that I didn't take a pic of. Would a sign from the 1970s cut it? The 1980s? Perhaps increasingly less so. The miracle of its survival is possibly less miraculous the younger it is, not only for the likelihood of it being painted over or its host wall destroyed, but also in the hardiness of the paint itself. And the pull of retrostalgia is less magnetic the younger it is. Also, there's the aesthetic element again - the older signs are often prettier: more care taken, more ornate etc. As per the letterheads on the Lewis & Skinner invoices.
