2019 nwot Mosaic Mini Boden 8-9 years boys UK flag & dogs

This is a new without tags rare Mini Boden boy dog tee in a size 8-9 years. I loooovvved this but it was outgrown before it was worn. It does run a little small. I love how the dogs are red, white & blue create the larger image of the UK dog tee. It is just incredibly interesting to look at. I could analyze it for a half hour and still be interested. So much detail. I love the intracacies. I've always loved photo mosaics because of the detail so I am thinking this is just called a picture mosaic. Someone set me straight with this terminology :)
