  • Patent number: 3977678
    Abstract: A novelty item of the disclosure includes a base, a first biological symbol of one sex mounted on the base projecting therefrom, and at least one biological symbol of the other sex that may be thrown over and caught by the base mounted symbol. The base mounted symbol is preferably of the male gender and the thrown symbol is of the female gender. Each thrown female symbol has its sex indicating cross configuration projecting from its circular portion for a distance approximately equal to the diameter of the circular portion so that the symbol may be thrown in a ring-like manner while still maintaining its shape generally like that of a biological symbol. The male symbol also has its sex indicating arrow configuration projecting from its circular portion for a distance equal to the diameter of the circular portion so as to have a shape like the female symbols. The male symbol is also preferably of the same size as the female symbols to give the novelty item an aesthetically appealing appearance.
