They'd be very difficult to identify, I'd think. Judging from the two-color printing, they were fairly cheaply produced, possibly by one of the countless companies, mostly throughout Asia these days, that produce generic low-end playing cards.
The interesting thing about them appears to be their age - do you have at least a guess as to a minimum of the number of years old they are? It might help narrow down the search a bit. Even low-end cards these days are often printed in three or four colors, whereas this one is just two, red and black - it is possibly due to how old the cards are and how expensive it might have been at one time to print using more colors.
Are the cards coated at all - do they feel like they have (or used to have) a slick finish to them, like some kind of plastic coating? Or are they bare, uncoated stock? Are the cards translucent - when held up to a bright light source, can you see the image on the reverse side of the card through the light?
