Thor has been staring at this for hours and he can't make any sense out of it, can you help him figure out what it is?

Commands that were run in order:
→ xxd -r thor.txt > thor.bin → file thor.bin thor.bin: lzip compressed data, version: 1 lzip -d thor.bin → file thor.bin.out thor.bin.out: JPEG image data, JFIF standard 1.01 → mv thor.bin.out thor.jpg
