James Malton print

I came across this print titled Vew of Trinity College seen through the porlico of parlament house (1790) .It interested me because my son studied there and it was by James Malton whos lithographes of buildings in Dublin Ireland are very popular and sell well in some of the main auction houses.

On researching iim fairly sure It is a print of an ink and watercolour on paper Purchased by the national gallery of Ireland in 1912.
on bottom left corner of my print is Graphic printers Limited, Dublin. i canot find anything about them or similar prints of the original from 1790 online ,and hope someone can maybe give me some pointers.

The print measures approx 17 and half inches by 12 and half inches.

There are other lithographes by James Malton showing up on line of similar views of Trinity college but not 1790 one.

Thanks for any help
