The new issue of Anorak Magazine contains a two page Mr Toast story. Anorak is a cool British magazine for kids. Kind of tough to find in the US but Mr Toast fans in the UK should be able to track it down.
Years ago at the flea market I found 2 large binders packed with a gum collection. The stuff ran from the 70's to about 1991. I have had the first book on my website for a number of years but I just got around to scanning the second half which mainly covers the mid 80's to 1991. I have it all up on Flickr
