>>16883913Definitely not Celtic.
The first one looks like the Nordic letter F, when it's not used as a letter, it can represent wealth.
The second one however, is a mirrored Asch, or A, in the Marcomanni system. If OP is a shitty artist, the first letter could be Marcomanni as well, Futhark F and Marcomanni Fehc are very similar (and have shared roots).
The last one looks like a mirrored Futhark "Th", but neither the sound nor the letter is found in Marcomanni.
F, A, Th?
Or maybe it's supposed to be read the other way around?
Th, A, F?
My best guess is meaningless gibberish scribbled by an amateur.
