The city of Lansing was going to hold a music festival, so it wanted to order several large colorful banners made from fabric with pictures of various musical instruments and musical notes to hang on the stage where the concert was to happen. It planned to order the banners from a banner manufacturer, Music Prints Inc., with whom they had worked before.

Anticipating that Lansing would order the banners, Music Prints Inc. sent Lansing the following letter:

City of Lansing, we have created new, large musical-themed banners that are 20' x 40' in size in the colors of blue, red, yellow, orange and purple. Because we value our relationship with you, we would like to offer five (5) banners to you, one in each color, for $500.00 each ($2,500 total).

Lansing immediately sent the following reply document:

Thank you for your very kind offer to sell us your new musical-themed banners. As you know, we also value our relationship with you. We would like to order all five (5) banners, one in each color. Please embroider "Lansing" on each of them. Thank you!

Music Prints Inc. immediately shipped the banners to Lansing. They did not embroider "Lansing" on any of them. When Lansing received the banners, it immediately hung them on the concert stage, but was upset that Music Prints Inc. had not embroidered the banners. It believes that Music Prints Inc. is in breach.

Lansing has contacted you, its attorney, for advice. Advise Lansing on whether there was an enforceable contract between the parties that required Music Prints Inc. to embroider the banners.
