(related to Problem: The Gentle Art Of Stamp-licking)

The following arrangement shows how sixteen stamps may be stuck on the card, under the conditions, of a total value of fifty pence, or $4$s. $2$d.:—


If, after placing the four $5$d. stamps, the reader is tempted to place four $4$d. stamps also, he can afterward only place two of each of the three other denominations, thus losing two spaces and counting no more than forty-eight pence, or $4$s. This is the pitfall that was hinted at. (Compare with No. $43,$ Canterbury Puzzles.)
