Souvenir Idea Required

[Biomech]

Good day!

I have a client who is looking to book my photo booth for a dual 16th birthday party. Now what we usually do is print 2 copies of each sitting (4 photos). One the guest gets to keep and the other one we stick into a guest book for the bride/groom, CEO or birthday person where we encourage the guests to leave a message.

I don't think it would be cost effective or practical and also too demanding on the guests to assign 2 guest books that need to be filled. So what I'm looking for is a souvenir product that can be duplicated at low cost with low impact on the guests. Maybe a standard printed photobook with no messages or something.

The end product of my service is maybe 400 individual photos on disc with 100 sets on disc and printed.

(sitting = 4 photos in succession, saved individually and in sets of 4, and dual printed in sets of 4, ie passport style strip, 2x2 grid etc)

Any ideas?
