You could try some charity shops you never know otherwise could be an idea to google image you could get the cover printed and then add their story inside or get a print of the book cover nicely framed that would be funky retro art for their house unique too ( well to any Ann and Barry couple lol)
Early this year i was at a meeting in my sons new school & they gave us his book list.
Anyway, afterwards i updated my status on facebook and said something similar to this " Just got our first school book list & not a sign of Ann & Barry", well the amount of people who asked me "who are ann & barry?", they thought they were other parents who forgot to go to the meeting or something. Only a few people got my status – lol. I thought everyone would remember Ann & Barry or maybe thats showing my age.
