I must be too young to realize that type writers had cursive fonts back in 1940's
I just did some quick searches and it looks like a "cursive" font. But most of the webpages are using type writers from the 50's, 60's and 70's. But this was used in 1949, So I guess this Parsons Drug Store must of had the first one.
found another cover, first day of issue and first day Newfoundland joins confederation, with a Canadian stamp.

And a "LAST DAY COVER"
