Prime Number Cards: Playing Cards and Large Letters

Each card with a playing symbol also has part of a letter faintly printed over the card in a slab-serif font, and it's anticipated that arranging all the playing symbol cards in order will eventually depict the whole message. All symbols appear on cards with prime numbers. 54 Prime numbers under 256 are as follows:

2 3 5 7 11 13 17 19 23 29 31 37 41 43 47 53 59 61 67 71 73 79 83 89 97 101 103 107 109 113 127 131 137 139 149 151 157 163 167 173 179 181 191 193 197 199 211 223 227 229 233 239 241 251
