From new old stock, we have a stapled booklet of 48 Valentine silhouette stickers - 6 different designs on each page.
These Presto Stick® self-adhesive stickers. These stickers are vintage, although the same patterns are made today. These stickers are from Eureka, a classic holiday decoration company. We expect that these are from the late 1980s.
These are VINTAGE stickers and the adhesive is probably not as good as it once was.
Use caution when removing the stickers from the booklet and, if the adhesive is less than perfect, please add glue or use an adhesive applier (like a Xyron).
We found it easier to peel the background off around the stickers - rather than taking the stickers directly off the paper. This is an old trick we learned from my grandfather, who owned a stationery / book store in the 1920s.
