Hi Emily, there is the possibility that these letterforms don’t stem from a font (as in printing typeface). The large size and the medium (cardboard sign, wooden crate?) don’t suggest the use of type. Chances are that this is lettering (custom letterforms), either done manually or maybe with stencils.
For a typeface that is roughly similar to “GLYN DANIEL” and was around in the 1950s, have a look at Cheltenham. It’s not a match in all details, but as a sturdy serif with not too much contrast, it might work as an approximation. If period correctness is not a concern, there might be better options. “INTRODUCED” is in a related bold condensed style. The characteristic detail here is the U with stem.
“MINERAL” appears to be in a different style altogether, see for example the E which seems to have no serifs on the middle bar. What’s special here is the M with the crossing diagonals. That’s a feature found in 19th-century faces like Old Style Bold, and was revived in ITC Tiffany (1974) – but those designs have large exaggerated serifs.
