How it is done, or how it is called?

Hello,
I visited Greece some time ago. On the streets where souvenirs are sold, photos that are transformed in an interesting style were also sold. I did not buy them on the spot and told my wife that I will make it myself from our photos, but now I cannot understand how to do it . Maybe if there are no specific suggestions, you can name the key words, so that I can enter them on google ? and I could find something similar. English is not my native, so I cannot figure out what words to look for.

Example what they made from photos:

is it just the effect on the border then you can google for "sloppy border" or "grunge border"

for example border 3 in this link

Assuming its borders only you can use One1 filter to add the torn paper border around your photo, if its turning a photo into canvas a filter can do that effect slso
Border effect (width of border can be adjusted to the thickness you prefer to get the painted look) . Quick snap shot in beige color
