My favourite find. Lovely Relief ware mugs.

I found these in a box of junk at an Automobile Show!
Love the colour and relief design. They stand about 4" tall and both are in lovely condition. I collect pottery, no particular type..just what I like. These really made me smile. I have researched to try and find the maker, maybe I'm looking in the wrong place?! Kronjyden Nissen keeps cropping up - beautiful relief ware. As far as I can see this stamp is JH and the writing below is hardly decipherable..ADINTUGAL? No it does not say made in Portugal..starts with an A? ends GAL? If you have any ideas please let me know, thank you.
