Typeface used in the Vikings series

that is to say a sans-serif font
you will find that here, category sans serif:
https://www.dafont.com/fr/

you will find shapes on the net for the drop cap, look for Celtic shapes

the proof, Vikings, that we can do it without the police:

a few sketches, shapes, a texture... anyone can imitate anything^^

I used Coolvetica:
https://www.dafont.com/fr/coolvetica.font

however, you will be forced to trim the tops of some stems at 45° so that it looks like the font from the series; I didn't find one with the same cut
to cut easily, you draw a 1px line starting from the tip and holding Shift, the line will automatically take the right angle and will serve as a guide to remove the excess
then, when you have typed your text and trimmed the stems, you draw three lines (^^) with the line tool on a new layer, you rotate it to 45° and duplicate it to place it on your letters
then you will need to set these lines to transparent so that your texture does not apply to them
do this at large size, otherwise you will have trouble selecting the lines

but still, it's the same with the modifications
afterwards, if you find coolvética too chunky, you can choose a thinner one
maybe it's also because I didn't want to copy exactly, I preferred to give it the same texture as the initial drop/lettrine rather than a metal effect
I like to redo it in a more personal way
but that’s a detail, you can do it differently :)

it must be found, wait a moment, I’ll make you a little list...

at Dafont:
- Code bold
- Cabin
- Florence sans
- Blue Highway
- Libération sans
- Petita

I stopped at page 12, I think you should find your happiness in there
of course, there are Helvetica, but not at Dafont
check if you have them in the Photoshop panel
also check in Confortaa, the Arial and the Myriad

Here are the Helvética fonts if you don't have them

I recommend downloading them, they are very useful for this type of poster.
