Other Formal Invitations
All other formal invitations are engraved (never printed) on cards of thin white matte Bristol board, either plain or plate-marked like those for wedding reception cards. Note paper such as that used for wedding invitations is occasionally, but rarely, preferred.
Monograms, addresses, personal devices are not used on engraved invitations.
The size of the card of invitation varies with personal preference from four and a half to six inches in width, and from three to four and a half inches in height. The most graceful proportion is three units in height to four in width.
The lettering is a matter of personal choice, but the plainer the design, the better. Scrolls and ornate trimmings are bad taste always. Punctuation is used only after each letter of the R.s.v.p. and it is absolutely correct to use small letters for the s.v.p. Capitals R.S.V.P. are permissible; but fastidious people prefer "R.s.v.p."
The word "ball" is never used excepting in an invitation to a public one, or at least a semi-public one, such as may be given by a committee for a charity or a club, or association of some sort.
For example:
The Committee of the Greenwood Club
