CHRIST, THE GOOD SHEPHERD MOSAIC T-Shirt

Canvas print of the KUFSTEIN TILE MOSAIC ... Austrian German "ICH BIN DER GUTE HIRT" = "I AM THE GOOD SHEPHERD". It references words found in New Testament Mark 10:11 and as prophesied in Old Testament Psalm 23. Found on a monument of a tomb in Central Kufstein, princely Tyrol state, in western part of Austria. I cannot believe the ceramic tile mosaic is in such good condition as it is described by an art historian as 19th century which means from the 1800s. The rest of this tomb looks old and worn. But, the ceramic tile looks to be in miraculous condition. Beautiful colours. Who would have the time and the patience to put this together by hand? The name on the lower far right (here being mostly cropped off) appears to say "P. Raimund Rudolf Gschopf who was born April 10, 1901 ... died February 7, 19... [the year of death is not showing in the photograph.] It also appears to say: "O[rder of] St R. [?] Dr. [of] Theol[ogy]. ReligionsProf[essor.?] Benedictine Abbey Al... [?]. I would guess the "P." would mean he was a priest. Parts of three other names / dates show and the form for January show this is the Austrian form of German. Some date from the 1800s (1858, 1869). Could it be that the priests themselves put this mosaic artwork together? Across the top, barely readable it has REQUIESCANT IN PACE ... a Latin phrase meaning REST IN PEACE. There appear to be words at the bottom in impossible to read old Gothic font script calligraphy that I just cannot make out at all. The artistic style appears to look like a blend of 19th Century German artist Bernhard Plockhorst's painting THE GOOD SHEPHERD (C. 1878) and priestly Orthodox religious devotional icons. The photographer, an art historian, also notes: "I, the copyright holder of this work [the high resolution photograph], release this work into the public domain. This applies worldwide. In some countries this may not be legally possible; if so: I grant anyone the right to use this work for any purpose, without any conditions, unless such conditions are required by law." 23 The Lord is my shepherd; I shall not want. 2 He maketh me to lie down in green pastures: he leadeth me beside the still waters. 3 He restoreth my soul: he leadeth me in the paths of righteousness for his name's sake. 4 Yea, though I walk through the valley of the shadow of death, I will fear no evil: for thou art with me; thy rod and thy staff they comfort me. 5 Thou preparest a table before me in the presence of mine enemies: thou anointest my head with oil; my cup runneth over.
