Hi all. I have an old family photo (ca. 1900). It appears to be a large sepia albumen print on heavy card stock.
The photo split down the middle many decades ago, and a long-gone relative used what seems to be (are you sitting down?) black electric tape to "repair" it.
Not much archival sensibility back in old Hungary!
The tape was dried out, and peeled off easily, but it left a discolored path containing small, hard, brownish granules well-stuck to the photo. Will a cleaner such as Pec-12 (never used it, just read about it) be suitable for cleaning it? Other ideas?
Many thanks! James, Brooklyn NY
