Harvard Med School alternates between glitz and sophistication.

Talk about two contrasting selling approaches. Harvard Medical School is currently in the mail promoting two newsletters:

* Harvard Men's Health Watch uses a #10 white envelope--no teaser copy, only the Harvard Medical School return address, and a live stamp.

Inside is a business-like, 6-page sales letter, black on white, from editor-in-chief Anthony L. Komaroff M.D. The only color used is a bright red FREE sticker on top of p. 1, to be placed on the light brown order form attached (with perforations) to the bottom of p. 6. A white BRE completes the package.

* Harvard Heart Letter uses a bright yellow, 9 x 12" envelope proclaiming in bold black type FREE when you reply within 9 days, and Free Stickers Enclosed. There's also sensational copy on front and back about sex, coffee, and heart disease.

Inside is a 2-color, 6-page sales letter topped off with the crimson Harvard logo and nine lines of red copy and three exclamation points. An elaborate order form features three differently colored stickers for Yes, Maybe and No.

Also included is a sheet of free, bright yellow smiley button stickers, which we understand are surprisingly very popular with Harvard's lists; a lift note; a crimson-colored list of 26 Revelations That Will Do Your Heart a World of Good!; and a black-on-yellow BRE.
